I fly the LA 7 a lot, and the Ki-61 some so I can tell you a bit about these.
The LA 7 is one of the fastest planes at low alt. I think it zooms higher than any other aircraft, so don't try to play rope-a-dope and try to out climb it. I don't turn hard much with it, but try to keep it fast. It has a small but deadly ammo load. If the pilot knows what he is doing, he will not fire until he is close in on your six.
The KI-61 is not a fast plane, but it can pick up a lot of speed in a dive. It will do a real sharp reverse turn (180) at low speeds, and has is quite good in a tight sustained turn.
Most my experiance with Yaks have been flying against them. I hear they are a good all around plane at low and high alt. At low alt, they can turn very well. They also have a real small but deadly ammo load.
I hope this helps, and someone can fill you in on the others.
I suggest to take some time and fly these aircraft a bit. The best way to learn how to kill them, is to fly them and let others show you
