It would be very difficult for anybody to travel by air without ID proof, as how would you prove that the name on ticket, and person travelling is same person. But fortunately, in domestic air travel in India, there are plethora of photoID proofs you could use (any one of them). Air India says:
For domestic travel within India, valid photo identification, namely, a passport, Income Tax PAN Card, Voterβs ID or Driving license is mandatory.
Also add Aadhar card to above list.
Note that any one of these is to prove that you are who you claim you are. If you are also claiming any fare discount, you might need something to back that up i.e. student card, army ID, age certificate etc.
If you do not have any of above in original, airport security might not even let you enter airport building. And evrn by rail travel, you need to provr yourself unless you are travelling in general unreserved class.
