Hi Andy,
just another character identified
. In your image with no 5 marked, we see Lt Neumann(Julius?). On my attached image we can see him standing next to Major Mettig, Kdre JG 54 back in August 1940, welcoming GFM Milch during juvenescence procedure of Geschwaderkommodores. At the time when your posted images have been taken, Neumann was still with JG54.
Cheers
Horst
