Hello Neha,
Currently, you are running coaching classes, so instead of foreign language I suggest you M.Sc. in mathematics because it will help you more in coaching and you already have mathematics background. So, M.Sc. is advisable.

You should appear for NET-LS exam, and join a college as a lecturer, after that, opt for Ph.D.

If you have opted for maths, you must be a brilliant student. You should opt for the course in which you have a keen interest.
