Specifically Cassie Sandsmark, as she gets her powers from finding a Utopian artifact. They had to call her Girl Power instead of Power Girl because of the existence of Karen Starr and Tanya Spears, two DC heroes by that name. Miles is inspired by Red Robin (the dead Falcon being a Jason Todd analogue, and he has wings like Tim did in New 52) and Sam I would guess Teen Lantern, as Green Lantern never had a sidekick until Bendis added her to Young Justice (at the end of that series, she became John Stewart's sidekick, and will be working alongside him and Far Sector's Jo Mullein in the new GL book).
They are indeed Utopian derived, but from an artifact, not genetics.
Yeah, Peter doesn't have powers - he's basically Jimmy Olsen - and yes, Miles is cast as Tim.
Originally, yes. But it was Blur in Robinson's ANAD series, and Aaron kept the name for his Flash analogue.
Invaders didn't have Blur. But yeah, it's him.
You called it! The solicitation for Amazing Shutterbug confirms that.
Yeah, and Young Squadron is the Teen Titans and Seige Society is Suicide Squad.
You're missing a couple more - The Curse of Brimstone (Ghost Rider) and New Challengers (another Fantastic Four take).
And Ant-Man. Though quite how Scott Lang still got his powers if Hank Pym isn't around... I thought for sure Scott would be powerless in Heroes Reborn.
