Need Clarification on Sale Deed & Agreement of sale cum GPA

Hi Team,

Thank you very much for providing this platform to public.

Party X,Y made an Agreement of sale cum GPA to party A,B,C,D,E (They are managing partners of a company).

Now, party A,B,C,D,E ( Vendor) sold part of property ( Means a plot) to party Q (Vendee) through a sale deed. In this sale deed, Party XY (Principals) name is there but their signatures & photos are not there.

Does this sale deed is valid because principals signature & photo are not there in the document but all managing partners have signed the document along with their photos and proof of identity??
