And some more style aping

Two of these should be obvious, but not so much the other two. Of the two possibilities for the top left one, I'm not sure what fits best so if there's a style that any of you style-savvy types can approximate and it's close to what I was thinking, I'll lean that way with it! (the style I initially went for was something I hadn't seen in years so I don't think it was quite accurate, so I gave up and did whatever with it. Still, I'm interested in what you see of it!)
Hint for the bottom: It's from a game and I pretty much yoinked an expression that's common for a character there.

Be warned, I'll probably do more! Haha!
