Among all the institutes which you mentioned, if you are aiming for USMLE then your preferred order should be:
UCMS - Best research opportunities and DU accreditation
LHMC - DU accreditation
VMMC - Good institute and no bond
IMS-BHU - same as the last option
SMS, KGMC & CMC - There is 2 year job bond in all the 3 institutes. Make the preference as per your geographical location(SMS>KGMC if you are from north).
All the best!!
