Dual

The better one is VIT-Vellore because it is widely preferred by the students for B.Tech and CSE. SRM is also good but if you get VIT go for it.
Both are good but the fee structure is a little high as they are private universities.
Salary packages depend on the candidate's skills and also the companies that offer core jobs. The candidates should have some additional skills to get placed easily.

You can apply for IPMAT. It's for the course IPM (Integrated Programme in Management) offered by IIM-Indore.

I prefer RNSIT IT is some how better.

It is one of the traditional universities and pursing law can be a good option from JMI.

If you are getting better colleges like IITs than you may go for nanotechnology otherwise M.Tech in CSE from AMU is a very good option. Facilities like a hostel, library, book bank, seminar hall, laboratories, etc. are awesome.
