Most of them, as others have said, yes can be queen mutational variants with the more powerful slimes like a Dark Slime Queen being extremely rare. Probably not for the Humpty Egg considering they don't divide but lay eggs themselves and can even give rise to more Jub Jubs. The Shoggoth is more complicated as it's unclear how they reproduce since going through fission and failing to divide when they reach a certain mass is how a Slime Queen comes to be. I would also wonder about Sea Slimes since they are more solid and jellyfish like. The others can but it depends on the rarity of the parent breed on how common a queen would be considering Slime Queens themselves are a rare variant.
