I would think that ashes Turtwig will evolve.
I see Turtwig evolving to Grotle or Torterra almost surely.
Chimchar will at least become Monferno. If Staravia hasn`t evolved yet, it will become Staraptor ( a desobient one,as Ash`s other fully evolved pokemon)
Buizel and Gilgar...Gilgar won`t evolve. I`m not so sure about Buizel, it can stay as it is,or not.
Piplup isn`t going to evolve untill she leaves the group,same as May. I dunno about Croagunk, I had a little hiatus before the Team Galactic battle episode. : /
Berlitz.
If Chimchar eventually reaches the evo of Infernape then it would be fully evo'd. You said leave it at Infernape.
Did you mean Monferno?
To answer the question, hopefully all of them, How can his pokes be in the level 60s and still not evolve? Its bs and one of the main things that pisses me off about the anime.
