M.A

Yes, you can apply but no correlation is there so it's better to go for M.Com or MBA or else you can go for any job for gaining experience as you are having commerce knowledge in your background.

It is not compulsory but after MBA, tour chances will increase for HR. Without MBA, you have to struggle very much. Therefore, I suggest you to pursue MBA.
