Mig-3
Yak-1
Pe-2
lagg3
Yak9-UT
Small notes:
Yak-9UT isn't historically significant even if it was cool, it is like 3xB-20 La-7 cool but historically insignificant.
I'd alter the list in following way and order:
Pe-2 - most important soviet dive+level bomber in WW2.
Mig-3 - the most widely deployed modern fighter in June 1941
LaGG-3 - the early type 7 with M-105PA engine - another major type that met LW in early war period
Yak-1 the 1941 version with M-105PA version, also as bonus the 1942 variant with PF engine version
La-5 - early 1942 variant (not 5FN with more much powerful Shvestov)
