I have the socket descriptor which is the return value of socket API. How can I use only this to know the family?

(Windows-specific): you can get SO_PROTOCOL_INFO socket option.

If successful, it would give you WSAPROTOCOL_INFO structure with iAddressFamily member.

You can call getsockname, but only after the socket is bound.
