Someone's Lego collection.
A fanart drawing
Probably one from a RPG game. But I have no clue because I'm not a fan of it.
Home-made is my guess.

Some anime I don't know about
Either Scooby Doo or some other Hanna Barbera show.
Nightmare On Elm Street.
Fanart or An Anime
Anime, most likely.
I don't know if that character was drawn-made or source from the internet.
