Help ID-ing guns in an anime.

[Zombees]

I went back to the Mezzo Forte page (which was the first article I posted on IMFDB) to post the remaining weapons I missed the first time. I'm currently having a little difficulty identifying some of the guns, and I was hoping you guys could help me out.

The weapons I couldn't ID are on the Mezzo Forte page,
http://www.imfdb.org/index.php/Mezzo_Forte
listed under "Unidentified".

Also, if you catch any mistakes I made, I'd appreciate it if you could point them out.
