Yours expected JEE Main AIR is about 198370. The admission in IIITs is seems difficult at this percentile. However you can be hopeful for the following IIITs during special rounds of counselling.
1. IIIT Dharwad
2. IIIT Kalyani

No, you are not able to get admission on basis of CBSE board marks. You have give JEE Mains for IIIT and JEE Advanced for IIT.

Yes you are able to get an admission in IIIT, Pune or IIIT, Hyderabad.

You can try for direct admission in BITS Pilani because you have top percentage in 12th pcm

You may get into some NIT's but IIT would be hard with such score this year.

Hello, You indeed have a phenomenal percentile. As per my understanding you need not even think of appearing for second set of JEE entrance examination planned for the month of September. With this percentile, I am sure you will definitely get admission in the desired stream in your desired NIT. Best wishes to you.
