Calem/Serena: conceptualized as 14 based on teraleak, but implied to be 16-17 by in-game dialogue

Ethan/Lyra: Definitely under 14 since we know BW was meant to feature the oldest protagonists at the time. I swear there was an old marketing blurb that said Gold was 10 or 11, but I can't find the actual source. With all the Red parallels, it would make sense for him to be 11.
Nate/Rosa: As far as I'm aware we have no information on these two unless I missed something in the teraleak. They're probably 14 though, with the obvious comparisons to Hilbert/Hilda made throughout the game.
Chase/Elaine: Anime-inspired game, so they're probably 10. If Red and Blue are still 11 in this game, it would make sense for the protagonists to be a little younger.
Victor/Gloria, Florian/Juliana: As far as I know we have nothing to go on. Could be anywhere in the 11-17 range.
