Can't read the text, so this is a guessing, but the plane on the last panel is a forward-swept winged jet fighter, which seems to be a Russian Su-47 Berkut. No idea about the plane in panel 3.
Also happy Hoppo is adorable.

I remember that plane. It's the ASF-X Shinden II, one of Ace Combat Assault Horizon's super planes. The shape reminded me of the X-02 Wyvern, which tipped me off on where to look.

Incidentally, the one in panel 3 is the CF-44 Nosferatu, also another of Ace Combat's super planes.
