I know that the two in the front-middle of the bottom row are Rosslyn Wemyss and Ferdinand Foch and the guy on the right is George Hope but can't seem to find information on who the others (Germans I assume) are.
Thanks.
At the bottom, from left to right: Rear Admiral George Hope, General Maxime Weygand, chief of staff, Admiral Rosslyn Wemyss, Marshall Ferdinand Foch and Captain Jack Marrriott, Naval Assistant to Wemyss.
People standing in the carriage are members of the French Army, closely associated with Foch. These are, clockwise, from top left: Commander Emile Riedinger, Lieutenant Paul Laperche (official translator appointed to Foch), Captain Joseph Martin Gallevier de Mierry* and Brigade General Pierre Henri Desticker, Weygand's deputy (all ranks as of 11.11.1918).
*A small anecdote here. Although generally unremarkable officer, de Mierry will make a name for himself in 1940 as the author of the report dated 18th May and stating that the German attack on France is a desperate reaction to Allied blockade and will most likely spell doom for Germans as this would also cut them off from the shipments via Belgium and Netherlands.
Edit: Hope is on the far left. On the right is Marriott.
Taken from the wikipedia page:
Key personnel
For the Allies, the personnel involved were all military. The two signatories were:
Marshal of France Ferdinand Foch, the Allied supreme commander
First Sea Lord Admiral Rosslyn Wemyss, the British representative
Other members of the delegation included:
General Maxime Weygand, Foch's chief of staff (later French commander-in-chief in 1940)
Rear-Admiral George Hope, Deputy First Sea Lord
Captain Jack Marriott, British naval officer, Naval Assistant to the First Sea Lord
For Germany, the four signatories were:
Matthias Erzberger, a civilian politician.
Count Alfred von Oberndorff, from the Foreign Ministry
Major General Detlof von Winterfeldt, army
Captain Ernst Vanselow, navy
The treaty only lists Foch, Wemyss and the 4 German attendees. On Weygand and Marriott I can't find any data yet. The wiki page doesn't tell me anything on that either. I'll keep looking.

Edit: comparing Weygan's face on his page and in the photo should suffice (second from the left).
All front in (dark) Naval officer dress are from left to right Hope, Wemyss, Marriott.
Edit2: German attendees: all the way in the back is the Major Von Winterfeldt. Theother three Germans I cannot be sure who is who exactly.
