Hello,
The best college for aeronautical engineering or CSE without any doubt is IIT-Mumbai.

As per me, the top colleges for aeronautical engineering are IIST-Trivandrum, Anna University-Chennai, and IIT-Bombay.

Depends on your bent of mind.
If you are a social extrovert person, go for business study otherwise engineering stream is rewarding.
Secondly, the place from where you do this course is important. Reputed colleges will give you a good start, irrespective of the course. So just see what is your academic performance and potential and decide accordingly.

The procedure is same but you just have to mention that you want admission through lateral entry.

Yes, you can join B.Tech after Diploma.
