Yes, you can. Wait for the results to get to know which one you can get.

Government colleges accept students based on JEE marks not based on class 12th marks, so depending on your caste category, you will be selected.

I don't know clearly, but I think B.Tech CS give you high salary than MCA.

JIIT University Noida is a better option for BTech CSE because of its All India rankings, acedemic environment and placement records.

You have been misinformed. With 5 years experience in after BTech you stand better chances in comparison to a fresh BTech to get admission in MS.

SRM University is better than KIIT.

If you get NIT, IIT or IIIT or any GFTI then it's far better. Other than that, you can go for some private universities like SASTRA, AMU, DTU-Delhi, or if you live in UP you can get colleges in UP like BIT, AKG, etc.
