Vanshika, I will list down the top colleges you can get admission in under JEE Main. This is based on your rank and previous year cutoffs. You can try for admission in these colleges for CSE or IT branch (decreasing order of preference):- 

National Institute of Technology Agartala

National Institute of Technology Goa

National Institute of Technology Hamirpur

National Institute of Technology Meghalaya

National Institute of Technology Puducherry

You can fill a large number of branch preferences in the JoSAA website. 

But again it depends on the number of students who appeared for the exam and as well as the difficulty of the paper.

For more information, you can refer to :- https://engineering.careers360.com/articles/jee-main-cutoff

Feel free to ask if you have any more queries.

Hope this helps!

All the best!
