Masters

Yes, after completing graduation, you will be eligible for doing PG Diploma.

Yes, you are eligible to take NET (psychology).

I am afraid 18 backlogs are too much to be accepted for any programme, let alone MS in any foreign country. Clear your backlogs first or pursue something else that is easy to clear like B.A.

Yes, if you get any job in placements from computer science, you can go through that. Otherwise, you can continue your post graduation.

If you want job opportunities, then do MBA. MBA has better placement and package as compared to other PG courses. You can also pursue B.Ed to become eligible for teacher and teach in inter-colleges.

Well, if you are getting admission in a good institute and in a course that you won't get here in India. Most people go abroad for Masters in Management. But there are even better colleges here in India that provide a very good package, so it depends on what your goal is and what you want to pursue.
