If all five are detonated simultaneous the concentration of neutrons and other rays will be higher. Each test would have interfered with the reading of fallout and immediate radiation of other test and the tests would make no sense. Even if it is an underground test, the nearest civil population is just few kilometers away. I was of an opinion that India should have conducted the test at sea as well.
This is why the first was thermonuclear device, the second was implosion type most probably with levitated hollow Pu239 pit and third one was linear implosion type with non weapon grade fuel.
This third one was the tactical weapon. linear implosion is what you require for a 155 or 208mm artillery shell.
4th and 5th were experimental devices. The 5th one was to see whether U233 can be used to put in the pit, as it is hazardous to handle and can be enriched from Th232 which India has in abundance. More of a metallurgy side.
This is my last reply on the subject so let me make it count.

Sir that might happen if all 5 were detonated in the same shaft .
All 5 were detonated at different shafts at appropriate distances from each other.
Underground testing negates emission of harmful rays and fallout , the very reason why underground testing is preferred.
Also if read my previous post you would have noted this
" why where the nukes detonated simultaneously " ( in two separate groups ) ? "
All 5 were not detonated simultaneously , according to official accounts
1st group - 3 devices were detonated simultaneously
Then the
2nd group - 2 devices were detonated simultaneously
Each test would have interfered with the reading of fallout and immediate radiation of other test and the tests would make no sense.
Yes for the layman's like me and you it won't make sense , but for the scientists who planned and carried out the tests , it would make sense.
Each shaft ( each nuke ) had its own sensors to record the data right at ground zero immediate to detonation ie within a fraction of a second and transmit the same before it got destroyed.
Also any sensors outside the shafts at a safe distance from all the nukes would have recorded everything from the simultaneous detonations. But Since the nukes were of different types and yield, the scientists would have been more than capable of isolating the specifics pertaining to each individual nuke and pinpointing the same from the collected data.
