Thanks Franck,
for your excellent haul...and ID! It is indeed Bf 109 G-8 W.Nr. 230 785 "Gelbe 11", 3./NAGr. 1, Fritzlar. By the way, there are already three left side pics known from this machine:

As for the other two machines,

This one looks like an Erla built Bf 109 G-10 (note the steep radiator and the upper position of the bigger 57 liters oil tank filler cap).
Finally the fourth one rings a bell: could it be "Gelbe 14" "TT+ED", found at Saint-Dizier in August 1944 ? The position of this machine in front of a Bf 110 G-4 is coherent with the already known shots:
