The first plane is the Mitubishi J8M Shusui, the second plane is the Tachikawa Ki-94-I, and the third plane is the Nakajima Ki-91 Karyu, which was a design copy of the Me-262, unlike the Kikka which, although resembling the 262, was an original design by Nakajima (and was actually intended as a special attack bomber, not a fighter).
The Ki-94-I evolved into the Ki-94-II with the original design never getting beyond a wooden mockup; the Ki-94-II was actually a conventional-looking aircraft, losing both the twin boom tail and push-pull engine configuration from the original design.
