As your rank is not so good, I think you also know that, so admission in NITs is not possible for you. But don't lose hope as there are many other colleges.

Pass in 10+2, A Level, IB, American 12th grade or equivalent with Physics, Mathematics and English as compulsory subjects along with Chemistry or Biotechnology or Biology or any technical vocational subjects as optional subjects with a minimum of 50% marks taken together in Physics, Mathematics and any one of the optional subjects.

Yes, you can take admission in that college.

According to me, yes, you can totally get admission in RAIT with 75.24% in Diploma.
However, I am not aware of the exact cut-off. For confirmation, check with your friends if there are any in the college or you can contact the college office to be sure.

I don't think so. There is an age limit for engineering since it is an undergraduate degree.
