hey! nice CSP's!
To help you out a bit on the unknown ones.
The green hat dude, he's called "Chavo del Ocho", very old show.
And the guy beside him, the silver haired-guy is called Gintoki from the Anime Gintama.
And I believe that the guy with the moon on his forehead is a guy from Tsubasa Chronicles!.
hope I helped!
