JG2 Richthofen squadron logos for all you painters!

Not quite.

1./JG 2 - correct (for 1940)
2./JG 2 - did not have a Staffel emblem, only displayed the Geschwader emblem
3./JG 2 - that blue triangle with the "Horrido" inscription and the sword is correct (for 1940)
What you have for 3./JG 2 was the Gruppe badge of III./JG 2 from 1941 on. by then most Staffel emblems were a thing of the past.

4., 5. and 6./JG 2 - no emblems beyond the Geschwader emblem
The emblem you depict as 6./JG 2 may be a personal or much later emblem. The emblem you assign to 4./JG 2 belongs in fact to 7./JG 2.

Your III. Gruppe emblems (apart from the "Thumb presses hat" badge of 7./JG 2) are correct, also with variations. However what you have as IV. Gruppe is a mix of various things which weren't used at the same time, for long or even at all.

10./JG2 was a semi-autonomous fighter-bomber Staffel - your emblem fits for that one - but it did not come into being before 1941. At that time the three other emblems, all of which were short-lived as the IV.(N)/JG 2 of early 1940, were long out of use. It's even questionable if any were used outside of propaganda shots.
