UGC NET for Sciences and other subjects demands a Post-Graduation and an OG Diploma, which is not equivalent to Post Graduation / M.Tech or M.Sc. Degree is not accepted. You should pursue a PG Degree like M.Tech or M.Sc. And then apply for NET-UGC Test.

Of course they are eligible. C+ and Java requires basics of Maths like say up to class 12th, not more than that. With practice in coding concepts are more solid.

There is not any bond restriction on learning any languages. You can learn freely.
