Yeah I see it this way (sorry to keep using other comics as example but... whatevs)

The turtles are the main characters. The allies are their well.. allies. Of themselves as a whole and individually (like April to all of them, or just Lucindra to Raph, etc.) Or even allies of allies like Kenya Leavitt.

So on an X-Men Wiki, for an article on Spider-Man he would be an ally. But it'd silly to have Cyclops as an ally. Or in the case of Fantastic Four, Johnny Storm wouldn't be one.

Now if it was one for a singular protagonist: i.e. Spider-Man himself, or let's say Batman... everyone who isn't the main character himself and helps out would be fair game.
