Who ends up with who??

I know Ron and Hermione end up together.
Harry and Ginny end up together.
George and Angelina end up together.
Who does the rest of Harry's 老友记 end up with?
Luna? Dean? Seamus? Neville? Cho? etc.
Does anyone know?
And who is Victorie? 或者 whatever her name was, the girl Teddy was 接吻 in the last chapter of The Deathly Hallows?
