If anyone knows who the others are, feel free to edit it, and I'll add the notes myself.

Well, I added Adriana Visconti and Kitano Furuko. The latter I am not too sure about, since I think it looks like her.

All character tags should now be listed. Only 2 witches that I am unsure of their names if they even have a name yet or will have one. (Witch on far right of top row(Gallian witch named Iris Monfort is the closest I could find, ears look different but hairstyle/color, goggles, and sword and shield all similar http://strikewitches.wikia.com/wiki/Unknown_Witches:_Secret_File ); witch between Raisa and Krupinski on 3rd row, possibly Enrica Tarantola(post #947996))

Added a few more notes...

Every witch that has a character design is here, Except for Cecilia Harris...

Plus some of the newer witches too :P (Kashida Isami, Grete Gollob, Wendelin Schroer, and Constantia Cantacuzino)

Indeed. Though I did notice he's also done Girls und Panzer character keychains. And I happened to spot Constantia's among 1 of the newer releases...

Never mind, found it among this: http://www.pixiv.net/member_illust.php?mode=medium&illust_id=34711395
