Might have to get this for the GA guest-stars. From what I saw in the panels you posted, there's Captain Freedom, Captain Tootsie, Daredevil, Doll Man (or Doll Girl, hard to tell from the pic but Doll Girl isn't PD), Black Terror, Silver Streak.
The gray Dragon is Malcolm, Dragon's son.
Got the comic. It's neither Doll Man nor Doll Girl but the Fox version of Phantom Lady.
Would have liked to see the GA heroes do more. You don't really get a handle of any of them or which ones have powers and which don't. Plus, a book of double page spreads is not much of a story (or an artistic achievement) when it's really only half of a book, the rest being a Vanguard story. Not much to really make me want to come back to "Savage Dragon" on a regular basis.
