Nice photo. My opinion: The man in the background right seems to be chief (in the rank of Gefolgschaftsführer). The others are probably some lower-rank leaders (Scharführer or so), according to the headgear. In my opinion it could be a non-official mission because they are not wearing the Grand suit (cf. picture 1 below) but some mixture with Kriegsmarine type jacket (for officer- and boatswain-ranked, second picture). Quite abviously, they are over 18, so they could dare smoking in that private moment.
