Hello Mangesh,
You have to complete your CPL, then you will be allowed to join IAF.
Possessing a CPL (Commercial Pilot Licence) is an added advantage. But, in order to join IAF, even CPL holders have to go through tough selection procedure that consists of written test, SSB (Services Selection Board) interview, medical examination, etc.
A candidate must have at least a graduation degree from a recognized university (3 year or 4 year graduation course). He/she must have undergone class 12th from science stream with physics, chemistry and mathematics as the main subjects. (This is also mandatory for CPL training).
The age limit is also crucial. For the flying branch, the upper age limit is 24 years. But for CPL holders, under the SSC (Short Service Commission) Scheme, the relaxed age limit is 26 years.

Hello Sourav,
I would suggest you to appear for IIT JEE and AIEEE. These two entrance examinations provide admissions to IITs/ NITs and other government colleges, which are cost-effective.
I would also suggest you to appear for individual state examinations (OJEE in Odisha, EAMCET in Andhra Pradesh/Telangana, COMEDK in Karnataka, etc.). These exams also guarantee you good colleges and serve as a backup in case things don't end up the way you've planned for IIT/ AIEEE.
Every state has its own share of good engineering colleges. So, don't underestimate or overlook them. They can prove to be vital. The more the entrance examinations you appear for, the more the options you will have for choosing colleges.
Certain colleges like SRM, KIIT (Odisha), GITAM (Vishakhapatnam) and ITER (Odisha) conduct their own entrance examinations. You can opt for these as well.
I hope it helps. If so, kindly, upvote this answer. If you've any further questions, kindly revert.
