Ted Ted graduated in 1971, but if we can find a way for them to know each other, I'm down! Alas, Ted was not part of the order. Regardless of all that, Ted will be will be friendly with EVERYONE. Including the Mehstoria.
Hermione I think they'd get on too. See above re: Astoria's mehness. She'll be pleased to see Alicia again. They should do stuff. Investigate and stuff. Peter should.
