If I get 600 in NEET 2020,what would be my fees to study in M.S.Ramiah medical college in Bangalore, but I am not from Karnataka?

You have to apply through the All India Quota counselling for the admission if you are not domicile of the state in which you are getting the admission on the medical or dental courses. The cutoff marks for the MS ramaiah college were 522 with the rank 14060. Even with your NEET marks you should apply for the govt. colleges through All India Quota and it would be easy for you to get the govt. medical college in any state. And the concern of the fees will remain the same if you go for the private college. You can nagotiate but that depends upon the college authority and unpredictable. You hve to go to the institute and inquire about it.
