I think that I agree with Canon couples

I like very much Neville/ Hannah, Luna/ Rolf and Draco/Astoria

I like the Ron and Hermione pairing and tgeGinny and Harry pairing, I think Neville and Luna would be cute. Draco idk about, not Astoria though

I like to pair the Hermione with harry

For Hermione Ron will always be perfect but if she hadn't ended up with Ron I think Viktor Krum would be good.

For Ron Hermione was, is and always will be the perfect girl there ever was.

Same with Harry and Ginny

-Ron

-Hermione

-Ginny

-Luna

-Neville

-Astoria Greengrass or whatever her name is who he ended up with

Hermione Granger-Viktor Krum

Ronald Weasley-No Opinion

Harry Potter-Cedric Diggory

Neville Longbottom-Hannah Abbot

Luna​ Lovegood-Ginny Weasley

Draco Malfoy-No Opinion
