Waqf property

I have a housing property and some shops into my name since 1983 from sunni waqf board at district Shahjahanpur Uttar Pradesh. This property was given me for 99 years and it was mentioned in the agreement between me and waqf board. The lease agreement was renewed in the year 2013. At that time all brothers, sisters and mother's name was included in the registered deed registered in registrar court. while earlier it was only in my name and the agreement was between me and waqf board in the year 1983. Whether the agreement may be changed and other family members name may be included in the lease agreement renewed in the year 2013 after 30 years. What is legal binding of this new agreement and whether all family members whose name is registered in the agreement are also became a tenant of waqf board and their liability has become due to pay rent of this property to waqf board on monthly basis. I request all advocates, please suggest and inform me here what is legal binding of this new agreement and that all my family members now bound to pay rent to waqf board or only I liable to pay rent to waqf board.
