Have you looked at the file PSF/PDB file? If the number of atoms is what
you expect it to be, then your system does have all 5 proteins. In that
case, what is happening most likely is, VMD is superimposing all 5 of your
proteins (because all of them have the exact same coordinates), so you are
only seeing one.
To get around this, give different chain name to the 5 proteins. You can
then select them separately using atomselect, and move them around using
moveby command. However, how you move them will depend on the details of
your system and what you want to simulate.
Hope this helps,
