IIIT

Your rank is good. You will even get IT branch in BIT-Mesra which is again a good college. You may opt for that college. But again, you will definitely get much better colleges than that. Apply accordingly.
Good luck.
Don't lose any chance.

You will definitely get NIT, IIIT and BIT-Mesra. If you prefer CS you will get it, you just have to shortlist some NITs and IIITs as per your choice. Check with the previous year's cut-offs of various colleges. Take some time write down the possibilities and apply for it.
Good luck.
Again you will get your desired branch.
Good luck.

You may get admission in NIT-Rourkela but definitely not a good branch like biomedical and INTMSC. You may get IIIT-Bhubaneswar and yes you can get into BIT-Mesra with a good branch as well. You can visit the official website of JoSAA to get the details.

Unfortunately, you cannot get NIT or IIIT, but you can get best government. Or, any private college. Try for them, and at least, you should fill up the counselling form for JEE. Hope you get any seat. Thank you.

Unfortunately, no. Try for government or other private colleges rather. All the best.
