These:
P-39, 5007 (from US)
Hurricane, 2952 (from UK)
P-63, 2421 (from US)
Spitfire, 1331 (from UK)
A-20, 2700 (from US)
and the P-40's and B-25's saw a lot of combat in Soviet hands.
I don't know the number of kills, but those aircraft are mentioned in many accounts of Soviet air battles. The P-39 is perhaps most prominent in the kills deparment as, for example, 3 of the top-5 Soviet aces flew the P-39, including the #2 ace (Pokryshkin).
