Your expected JEE Main AIR is about 139178, Which is very good enough for getting admission in Amrita Vishwa Vidyapeetham in desired engineering branch.

No, you cant application is must for BITSAT.

Yes, you can get your seat in aerospace if you apply in stream1. If you don't get in 1st counseling don't be panic maybe you can get in last counseling. Try up to last.

You can get any seat definitely in sastra wait upto 3rd counselling after attending 1st counselling. You can get a better branch seat. As you didn't mention any priority of branch.

I think it won't be sufficient to get a CSE seat in SASTRA. If your JEE AIR rank is below 30,000 you can get a CSE seat.

If you are ready to take any branch seat maybe you can get something in 3rd counselling . But you are expecting ECE seat which is not even possible . If you want to apply in stream it requires 970-985 marks in IPE and the Jee AIR rank has to be in below 40,000
