Hello Aryan,

Jain University is a very renowned college for Aerospace Engineering. It comes just after the IITS in this course. As for the fees,  they charge a total of 1,60,000 rupees per year. Since this a 4 year course,  the total fee amounts to 6.4 lacs. If you get IITs then definitely go for the IITs. But if you haven't got any IIT then Jain University is a safe choice.

However this university doesn't provide good placements for aerospace engineers (according to student reviews) . But the faculty is extremely good. So if you want to check any other colleges out just to be safe, you can look at:

1. Madras Institute of Technology

2. HIT,  Chennai

3. Nehru College of Aeronautical and applied Science

4. IIST,  Thiruvananthapuram

5. IIT,  Patna

Hope this helps   :)
