If so, which wind tunnel did DRDO test their HSTDV models?
Most probably.
This one, probably :
There is another in the making. This one here, don't know the current status though :
hypersonic shock tunnel at DRDL Hyderabad, with a 1m test section and max Mach 10. At right, the new VSSC hypersonic complex, both with 1m test sections and Mach 12 max velocity. The tunnel with large tanks is blowdown-driven.
Photos of test articles in DRDL Hyderabad's hypervelocity range. Perhaps these were maneuverable reentry vehicle studies for the Agni-series? Those fins make it look awfully similar—but not identical—to the Agni-II's warhead.Photo credit: IISc Bangalore

BrahMos-II hypersonic cruise missile
News reports of October 2019 indicate that DRDO has commenced work on a next generation hypersonic weapon – a missile that can travel at five times the speed of sound, or a little over 1.6 km every second, and for testing and fine tuning the technology a wind tunnel will be operational soon. Defence Minister Rajnath Singh is expected to inaugurate the wind tunnel facility soon. The race to acquire hypersonic weapons technology is heating up globally. China, Russia, and the United States are testing hypersonic weapons of various types to enhance strategic nuclear deterrence and strengthen front-line combat units. Existing intercontinental ballistic missile (ICBM) re-entry vehicles also travel at those superfast speeds, but the hypersonic glide vehicles now in development are far more maneuverable, making their tracking and interception nearly impossible.
Hypersonic weapons are specifically designed for increased survivability against modern ballistic missile defence systems. Hypersonic vehicles typically consist of a Supersonic Combustion Ramjet, or Scramjet propulsion system to enable such high speeds. A Scramjet engine is an engine that uses 'air breathing' technology; the engine collects oxygen from the atmosphere as it is traveling and mixes the oxygen with its hydrogen fuel, creating the combustion needed for hypersonic travel. This is different than a traditional ramjet, which is used on space shuttles and satellite launches. In contrast to conventional Reentry Vehicles (RV) that travel at supersonic speeds (between Mach 1 and Mach 5), hypersonic weapons travel along the edge of space and accelerate to between Mach 5 (around 3,800 mph) and Mach 10 (over 7,500 mph). While conventional ballistic missiles are launched at steep trajectories that inhibit speed during the high friction of launch and reentry, hypersonic missiles glide atop the atmosphere while engaging specialised jet engines to perpetually accelerate up to hypersonic speeds.
Ability to travel at ultra-high velocity is the primary appeal of hypersonic missiles because it extends their range and allows them to bypass modern layered missile defences. Hypersonic missiles are capable of delivering conventional or nuclear payloads at ultra-high velocities over long ranges. Hypersonic missiles can be fired from the last stages of an ICBM or Submarine-Launched Ballistic Missiles (SLBM) and skip along the top of the atmosphere using specialised jet engines to accelerate to hypersonic speeds. Alternatively, hypersonic missiles can be launched independently or released from a bomber, similar to cruise missiles, before accelerating to ultra-high speeds.
Falcon HTV-2
The US has invested in research and development of a hypersonic missile called the Advanced Hypersonic Weapon (AHW), which uses boost glide technology to propel warheads. During a test in 2011, the glide vehicle successfully struck a target located 3,700 km away with precision. Concurrently, Lockheed Martin has developed a hypersonic vehicle called the Falcon Hypersonic Technology Vehicle 2 (HTV-2), which is a maneuverable rocket-launched aircraft that glides through the Earth's atmosphere at speeds up to Mach 20 (13,000 mph). US is using the HTV-2 and AHW in its 'Prompt Global Strike', which would allow the US to launch a hypersonic strike against targets anywhere on the planet in less than one hour.
Russia has been designing and testing various hypersonic glide vehicles (HGV) and hypersonic cruise missiles. Avangard, a hypersonic glider has been tested multiple times since February 2015. It can reach speeds of Mach 20 (15,000 mph). In March 2018, President Putin announced completion of testing and commencement of its series production. It was then set to become operational in late 2018 or early 2019, nearly five years ahead of schedule. India and Russia are also jointly developing the BrahMos-II hypersonic cruise missile, testing of which is ongoing. BrahMos-II is likely to enter service in Indian and Russian military in 2025. BrahMos-II will be one of the fastest hypersonic cruise missile in the world reaching speeds of Mach 7 (5,000 mph). Russia's 3M22 Zircon anti-ship hypersonic cruise missile was successfully launched in June 2017, reaching Mach 8 (6,000 mph). KH-47M2 Kinzhal is another Russian hypersonic cruise missile. It can reportedly travel as fast as Mach 10 over a distance of 1,200 miles. Kinzhal is designed to counter US missile defense systems like THAAD and heavily defended US aircraft carriers. As of May 5, 2018 ten MiG-31 fighter jets have reportedly been fitted with Kinzhal missiles.
China has been developing its hypersonic weapon capabilities with advancements in both hypersonic glide vehicles (HGV) and hypersonic cruise missiles since 2014. China's hypersonic glide vehicle 'DF-ZF' had undergone six plus development tests between 2014 and 2016. Launched during the last stage of a missile, the DF-ZF can reach nearly 7,500 mph (Mach 10), as well as maneuver to avoid missile defences and zero in on targets. Scheduled to be operational in early 2020, China claims it can attack ships at sea with precision. PLA has also been testing its DF-17 ballistic missile combined with an HGV. The DF-17 underwent two tests in November 2017. It has an estimated range of 1,100 to 1,500 miles and can reach mach 10, without losing any of its maneuverability. The DF-17 combined with HGV is also expected to be operational by 2020.
India's missile programme is impressive thank to the initial push given by former President A.P.J. Abdul Kalam and BrahMos-II will be good addition to India's combat capability. But considering the level of R&D and focus by China in next generation weapon systems, the DRDO will need to work with top speed in conjunction the private industry. China appears to be racing ahead not only in swarm drones warfare but there is also speculation that China may have raced ahead of the US in stealth technology.

SR71 was Turbojet +Ramjet, SR 72 is the actual project where Americans are trying to achieve hypersonic speed using Turbojet +ScramJet, ISRO did DMR by combing RamJet+ScramJet
Maybe the difference, in theory, I am just quoting from ISRO Page
A dual-mode ramjet (DMRJ) is a type of jet engine where a ramjet transforms into a scramjet over Mach 4-8 range, which means it can efficiently operate both in subsonic and supersonic combustor modes.
India ready to test Hypersonic Glide Vehicle
HGV-202F an indigenously developed Hypersonic Glide Vehicle by HTNP Industries is prepared to conduct it's first Hypersonic test which was being delayed amid Coronavirus pandemic.
HGV-202F by HTNP Industries
Akola, Aug 12, 2020 (Issuewire.com) - The invisible threat of Coronavirus pulled up dark clouds over Hypersonic testing of it's Hypersonic Glide Vehicle (HGV) HGV-202F that have been developed by Indian defense StartUp HTNP Industries.
Warhead was set to test under the supervision of respective government organizations in June but has to be postponed till the situation normalizes.
The co-founder and CEO of HTNP Industries, Shantanu Gawande have yet to clarify the test schedule of HGV but is expected to do it soon in this month. The HGV is being developed by the Advanced Hypersonic department of HTNP Industries in HTNP Industries's Material Science and Engineering lab (MSEL). HTNP Industries CSO Saurav Chaudhari did said about the progress of HGV and its glide path.
HGV-202F is HTNP Industries's ambitious project to develop the country's first HGV. Following Russian Avangard, Chinese DF-ZF and US's Common Hypersonic Glide Body (C-HGB), HGV-202 is faster and has better accuracy than Chinese DF-ZF.
This test of HGV-202F is about the maneuverability of the Warhead at Hypersonic conditions.
The MSEL has issued a set of guidelines for their scientists and other staff on the prevention of coronavirus infection. As part of precautionary measures, bio-metric attendance has been stopped and priority is being given on complete sanitation of surfaces frequently used by staff.
Meetings and discussions are being done through video conferencing on Skype to ensure the safety of staff and to prevent the spread of Coronavirus. All necessary precautions and guidelines are being followed by the company and its labs.

this HTNPIndustries is supposedly developing an ICBM called Mrgavyadha with a Max velocity of Mach 46.5
Like USA we should also invest in hypersonic artillery shells. They are cheaper than missiles, could be deployed in various platforms ranging from land systems to warships. Their low cost would help us to produce them in much more quantity then missiles while they will offer almost same capability in comparison to missiles.
