The show actually doesn't have them use aliases at all until said episode, in which most of them adopt the aliases given to them in the titular fan fiction. Honey Lemon outright asks the author (a girl named Karmi) to change her own alias (Tall Girl) after showing insecurity about her height, as if Karmi is the one who decides the official codename.

And Hiro's alias, Captain Cutie, does carry over into future episodes, being brought up again in episode 18. Though after editing the pages, I was catching up on the show and in episode 17 (Big Hero 7), Fred does tell someone calling him "Lizard Guy" that his alias is actually Fredzilla.

So maybe Fred's should be changed back, but at least for Hiro, it actually is Captain Cutie at this point (which is hilarious). And through the scenes of her dealing with her codename in the episode, I would imagine Honey Lemon is keeping her codename as well. Wasabi, Baymax and GoGo could probably be changed back as well, though. Unless they get their aliases confirmed in a later episode.

With the last four episodes of the season airing within the next month, it should be fairly easy to glean enough knowledge to make a decision on the last three.
