Given one of the common method of naming usernames on certain social medias, I think I can guess ages that are relatively canonical.

Papyrus: 21

Undyne: 25

Napstablook: 94 Yeah but it was never stated that the game takes place in 2015. The year Chara fell is 201X and it is stated that many years passed between Chara's and Frisk's fall, but we don't know what year it is in Undertale universe during Frisk's adventure. Undyne's birth year might be 2091... That might be true, huh...
