>>13852772 is a full flat zero grind (i guess you could call it a full scandi if you want I wouldn't hold it against you), 3 is a scandi, 5 could be called a saber (so could 3), 6 is convex, 1 is hollow
some things called scandi's also have microbevels
the terms aren't always mutually exclusive. you can have a saber with a convex edge, etc.
And some sharpening nerd may correct me as well.
