Hello can anyone tell me what medal he has on his left ? Thanks

NSFK glider proficiency badge.

Thanks do yoy maby know anything about his uniform what he was in luftwaffe?

His collar patches suggest the rank of Gefreiter, though he should also display the single stripe for that rank on his left sleeve.

 

His collar tabs would appear to be in Goldgelb (Gold-yellow) which signified Aviation troops (pilots and ground personnel) and also Fallschirmjäger  (Paratroops). They might also be in the later White of the Luftwaffe Field Divisions.

White piping is for the Herman Goring division.
