Not certain what the plane on the bottom right is. Looks a lot like an F-CK-1, though the vertical tail doesn't quite match.
It's definitely not any of the planes that were in AC4.

Yeah, the F-CK-1 is in the pixiv post's tags but I was reluctant to add it since I know that's not in AC4, though that's probably enough to confirm it now. The pixiv post is also tagged with the F-20 Tigershark, taking another look at it I can see it now.
