I like your
Kobac ... early-model MiG-21 meets MiG-23

And your Fairey
Fantôme monoplane is very tasty! And plausible

One that I can't identify is your '49C' ... although it has a decided Émile Dewoitine vibe going.
Also like your
Twin Defiant (although she looks like a large tail may be in order). Are those
Peregrine engines?
