First of all please don't be so paranoid
MBBS is just an educational course and not a hell
The way you have been excited is very Jubilant to see but weather with respect to Hind institute or with any other medical school or college or university they can't really force you to stay in the hostel unless of course there are residency shoes and your evening duty is where it is convenient to you to not purchase some other residency and stay at the hostel which is being provided within the campus of the institute
otherwise there are no such issues at least with Hind institute and you should make it comfortably from your home even if you do not stay the hostel it is not a crime and being a day scholar is absolutely normal

Hello Azaan

No dear.! It's not compulsory for the medical students to stay in hostel.
The College provides hostel facilities within the college for boys and girls which would be useful for the students who live outside Lucknow.
