Good luck.

For Diploma in Plastic Technology, eligible candidates need to appear for the Central Institute of Plastics Engineering andTechnology JEE (CIPET JEE) conducted by the college. Admission is through institute level counselling based on the rank obtained in Central Institute of Plastics Engineering and Technology JEE (CIPET-JEE). For B.Tech in Plastic Engineering, mandatory subjects are Mathematics, Physics, and Chemistry. Candidates must have secured 60% aggregate marks in Physics, Mathematics and Chemistry.

Yes, you can try if your luck is good. Then, you can get in 1st round.
All the best.

A main campus is always better than an affiliated campus. SRM and VIT are no doubt one of the best private institutes in India. In my opinion SRM Chennai (main KTR campus) is better than VIT Bhopal. And with this rank, it would be easy for you to get in SRM.
All the best!

Admissions are open. You need to decide on the college where you wish to apply.

Sorry to say but in your rank, you will not get CSE try for another branch.
Good luck.
Upvote if it is helpful.

Yes, but you have to defend for it.
