If you have a very good JEE score you will definitely get a seat in MSRIT.This campus is highly reputed and students with good score usually join MSRIT.

No, there is no such criteria by which you can get admission in SPA by UPSEE. You have to clear JEE paper 2 for this.

List of popular colleges accepting NATA scores are mentioned at the link provided below:

based on your HSC marks and NATA score it's quite difficult as MIT is the top institution for architecture itself and you need to be loaded with extraordinary marks and certificates just to enter into the competitive environment of MIT.
Now I don't know if you are talking about Massachusetts institute of technology or Manipal institute of technology, as many people get transferred from Indian architecture institution to the MIT, Stanford and London college of architecture so :)

There are no chances of getting admission in any NIT, as of ST category the seats close within 1000 rank.
