Scanned photograph from my father's album.

The individual in the front in the cap, 1 on the silhouette, is the "Skipper" and Rushen Castle's first Commanding Officer, Lt.Cdr. Colin Warwick, DSC, RNR.  Standing behind him, second from the right, is my father, then Lt Eric Clubb RNR 5.

I believe from information received in relation to another photograph, 2 may be the Navigating Officer,  S.Lt. Alan Weeks, RNR.  Also I now know 6 to be Lt. Clifford Gwinnell, RNVR, the Gunnery Officer. 

But what about the remaining two - can you help?  If you can, please let me know with reference to the numbers on the silhouette below.
