MS in CSE is a very competitive course, and all the colleges/universities you have mentioned are under SPP. SPP courses get high number of applications, so it becomes even more competitive. However, your profile is decent. You should get accepted in at least one institute from the above. Please do mention if you will take GRE in future or not. GRE scores might prove to be important in your case.

There is no average salary figures anyone can provide you. The reason being that the kind of job you will get after finishing the course will depend on how good or bad you are at your course.
You can check the college's website here to get more information.

A university will never guarantee a job Abhishek. These universities you mentioned are pretty well known for its undergraduate business studies and you will have enough exposure. You must ensure your own academic performance, communication skills and a good performance during your internship. Keep your head strong and you will do well.
Best Wishes
