Names of novels I read in MS

MS as in middle school.

There are a couple of novels that I remember reading is middle school, but can't remember the titles of. I remember finding them pretty interesting, and I want to read them again, so if any of this sounds familiar, pls drop the names of the novels that you think might be it. Even if it's not, I might just check them out either way.

1. An outcasted kid with a diamond shaped birthmark on her face joins a circus (?) I'm like 70% sure that there's magic involved, but I could just be misremembering. Also her birthmark makes her "ugly" which us why she is outcasted.

2. A kid's single mom (or aunt) suddenly dissappears without a trace and she tries to look for her. I remember that the mom/aunt left a note of some sort pinned to the fridge. I don't remember much.

3. This one's like a retelling of the red queen's past from Alice in wonderland (i think) When she was younger, she fell in love with a jester. But the king/ruler of the land she lived on was infatuated with her. In the end, the jester was murdered (i forgot who did it) and that's how she became the queen, bc she wanted revenge on the jester's killer. It was smth like that, probably a lot more complicated than that lol.

4. Another Alice in wonderland-type story. There's this girl who has a hobby of framing butterflies and hanging them in her room. She likes to draw, and she's depicted as this weird girl at school. She meets this guy and she agrees to meet up with him at a skatepark (?) I forgot the rest, but I'm like 99% sure there's magic and other worldly powers involved. Might even be a popular YA novel.

5. Don't remember much abt this one (shocker, I know) but the girl is a tutor at her college (maybe high school) and she tutors this one girl who is popular (?) but she finds out that the girl is secretly pregnant, but it's the result of rape by this one guy, and they become friends, i think.

6. A book where it was in diary format and the girl was young and explaining how her days passed while she dealt wirh depression and using drugs, and basically going down the wrong path. Don't remember much else. But the book's atmosphere was like super depressing.

And that's abt it. I'd really appreciate any help pls and ty
