No
well ash's squirtle will never evolve because of the squirtle squad and his bulbasaur chooses not to evolve, in episode 51 bulbasaur was going to evolve along with a large group of other bulbasaur but it chose not to, so it never will.
He's been a squirtle for 12 years now, I don't think he'll ever evolve in his life time. Besides, Ash's Squirtle isn't even on his team now.
No, not in any of the Pokemon Anime Series cartoons, but he does work with Wortortle and Blastoise while volunteering for the "Squirtle Squad".

No, Ash's bulbousaur does not evolve, but May's does.
yes it does
yes
Probably.
the squirtle squad
Ash's Pikachu, Squirtle and Bulbasaur have never evolved and they never will.-Pikachu is a main character and therefore his appearance changing would be a ton of extra work, also it would not look right for the main character to change.-Bulbasaur and Squirtle are no longer with Ash and Bulbasaur currently resides at Professor Oak's lab while Squirtle stays with the Officer Jenny in charge of the Squirtle Squad.To evolve a Pikachu in-game, use a Thuderstone on it.To evolve a Bulbasaur, level it up to level 16.To evolve a Squirtle, level it up to level 16.As seen in "Bulbasaur's Mysterious Garden" Bulbasaur tried hard not to evolve.In the episode "Electric Shock Showdown" Pikachu had a chance to evolve into Raichu, but did not want to.Ash's Squirtle has shown no opinion towards evolving further but because of its ties to the Squirtle Squad and its friends there, it's unlikely it will evolve.
In a world where characters stay 10 forever, I don't think Ash's squirtle is any sort of age. Ash's squirtle is not on the show any more.
