Those are Countries First Jet Aircraft/Experimentals and so they are not fighters.

Gloster-Whittle was a fighter, it had provisions for 4 x .303 Brownings.

He-280 was also a fighter.

Ikarus J-451MM was a fully equipped light attack aircraft.

These are no different than some of those already listed that didn't go beyond a handful of prototypes.
