Sir/ mam I have only 16 marks in jee main and 64 marks in MHT CET can I get admission good college or not please please answer me

It depends on what college you want.
Government colleges at this score are simply not possible unless you have reservation.
At your score it is difficult to get into a good college in Mumbai or Pune without any reservation.
You can surely try getting into any private college by waiting for subsequent lists in admissions process.

Some good colleges also have management seats based on exams they take on their own.
Try those too.
Thank you
