Herman- Not too impressed with the way she's dealing with that, but considering Beatrice did the same with Donny 6 years ago, he'll come around.
Beatrice- Perfectly understands Hermione's reaction, but would give her the same advice she was given 6 years ago. Don't keep it to yourself, they have a security team for a reason.
Mandy- Was in the DA starting in 7th year. She fought and nearly died at the Battle, then spent 2 years at the Ministry training as a Hit Witch. She has a lot of respect for Hermione for everything she's done.
Justin- Same as Mandy pretty much?
Finley- He only knows her by name, really.
Matthew- If she's a client of the bakery he'd know her. And well, he's been 'around' the Weasleys because of Charlie/Hestia/Tonks too.
Michael- Well he dated Ginny and held off the DEs when Harry went in search for the diadem. He has a lot of respect for Hermione and looks up to her.
