With this EWS rank I don't think you are getting any branch in any of the IIITs/NITs taking admission through the JOSAA counselling.

Moving to the other part of the question, HBTU Kanpur was once the top college under AKTU but now it is a university on its own taking admission through JEE MAIN score so if you are getting any branch over there I would say do not miss it by any chance!
