AGMC (Tripura) is around Rs 66500-75100 per year which will be around 3 lakhs total + hostel and books fees.

RIMS (Manipur) total is around Rs 6400 per year from their official site which is around 30,000 total + hostel and books fees.

NEIGRIMS (Meghalaya) total is Rs 6020 per year which is again around Rs 30,000 total + hostel and books fees.

This is based on past year fees but to be sure you should directly get in contact with the college of your choice for MBBS course.

Hope this helps.
