Three of these 'groups' don't actually appear to be groups of anything, I'm afraid, and the explanations leave me no wiser.

The group of prophets in Christianity is good, and has a clear red herring. But try not to mix names of fictional kings with names of people whose surname is King; this is not a cogent group. You've named some rappers, but if the link is their real forenames then Jay is not Jay Z's real forename. And I can't see the link in the other group, which you don't define in the explanation.

I've tried to be constructive so please accept the feedback in the spirit in which it's intended.

Nope. Not for me. :(

no - obviously
