Yes.

I don't understand what you want to do here.  pdb2gmx can deal with multiple 
proteins in a single coordinate file, with topologies written for each depending 
on what you choose for the -chainsep option.  Different chain identifiers or TER 
delimiters can be used to indicate that a new molecule has started.
