Some of these designs are just baffling. Are all of those Naruto clones Haxorus?

The artist name translates from 片桐 to "Katagiri". There is already an artist with this name, though.

For the currently untagged charas:
middle row left of Flygon : Arcanine(?)
middle row left of Arcanine(?) : Vaporeon{?)
middle row between 2 Haxoruses : no idea
bottom left : Ditto(?) Weezing(?) Musharna(?) Spiritomb(?)
bottom row right of Garchomp : Latias? AZ's Floette?
bottom right : Absol(?)

Bottom right seems to be Houndoom. Bottom left of Garchomp is most likely Latias. Middle Row blue girl next to Arcanine(?) could be Kyogre. Also between the two Haxorus clones, the claws scream Zangoose but the color scheme doesn't. Unless it's a shiny...

Top row between Serperior and Liligant is Tyrantrum, for sure. Middle right looks like either another Milotic or Sylveon, or possibly another fairy type.

No idea for the ones on the bottom that are not identified yet.

E: while I was forming this post someone tagged Tyrantrum. Good Job, whoever you were.

It's Katagiri Hachigou, who already has their own tag.

How is that girl Kyogre? The shade of blue is completely different, she certainly lacks Kyogre's signature red patterns, not to mention those head fins which would make her either Vaporeon or Gyarados.

That's no Sylveon, just another Milotic, and that's not Delibird either, that was Latias (Delibird don't have blue color anywhere...)

Haxorus, Goodra, Milotic, Serperior, Tyrantrum, Liligant, Togekiss, Noivern.
Flygon, Arcanine, Vaperon, Rayquaza, Jolteon??, Haxorus, Sylveon I think but probably Milotic
Gastly, Latias, Garchomp, Rayquaza, Lucario, Milotic, Absol.

I dunno why... but the only one untagged feels like a Sandslash to me... don't you think?

I'm going out on a limb here, but I think the last one untagged is a Vespiqueen.

The untagged ones are a Shiny Chandelure and yet another Milotic. I've trolled the official website enough times because I love the Pokemon they draw XD

Well, it's added now.
