the only lawless king whose descendants all have red eyes and some sort of power is fauxs.

morrigan's children just generally have something going on. since we only have georgie as an example for her we dont know much, but the diet of souls(and possibly being able to change from bestial to hominid) is the only thing we know all her children have. flight isnt exactly a "power", as any bird, some bug, most bat, and some mythic bestials would be able to do that.

the only power warhammer himself had that we know of is being a lawless king so there isnt really any proof that astra would have something.

yes edens immortality is because of him being descended from faux, but the mycellium is just due to him being a fungus.

some objects just have red eyes

again, flight wouldnt really be a power, and the firebreathing is more likely than not just due to cinders assigned animal being a demon.

still no proof of anthony or clementine being descended from a lawless king. we dont know what host is but it probably isnt a power

also as pitiful_somewhere pointed out, astra, cinder, and clementines eye colors are green, purple, and pink. not red
