Yes, you are if your AIR is 18360 but if this is your State rank then maybe not. From now on board marks don't affect JEE rank.
Good luck!

No. Unfortunately, as of now, SSC boy students don't get hostels.

Self-sustaining course (SSC) just has extra fees compared to the regular course. The duration for both is the same, i.e., 4 years.

For B.Tech regular, you have to appear for JEE Main examination. OJEE conducts the counselling programme based on JEE rank. For B.Tech lateral entry (after Diploma), OJEE exam is required, not for regular B.Tech.
Hope that helps :)

Yes, definitely you will get in CET BBSR or IGIT Sarang as per your rank card.

Yes, you have a very good chance to get into VSSUT with that NATA score. But I'm not sure that your 12th marks affect your chances. So don't forget to contact the college once.
