What are some status kanji?

I don’t know what to officially call them. Like how in English lists we might see “Y” or “N” for yes and no, for Japanese I’ve noticed in lists, status boards, or on signs/forms

済 for “registered” or “in possession of”

満 for “full”

空 for “spaces available”

代 for “proxy”

etc.

What are some other commonly used single-kanji for such purposes? I’m specifically looking for “accepted” and “rejected” but any and all would be interesting too.
