What ever happened here? Who's who?

That was from Life With Archie and it was when Veronica was being set up for some sort of white collar criminal case. If I remember correctly, Sam Hill found the evidence needed to clear her. I know that there was a character reveal, but don't remember where.

Can anyone remember who's who?

I'm missing some, but I'll take a stab at about 80% of them (this is without looking at LWA):

ON THE LEFT of Lawyer
Front Row:  2 more lawyers (?? - not sure if they were more than incidental characters)
Row 2:  Ginger Lopez, Frankie Valdez, Shrill, Mr. Weatherbee
Row 3:  Evelyn Evernever(?), Pop Tate, Svenson, Mrs. Beazly, Ms. Grundy, Prof. Flutesnoot
Row 4:  Shary the spy girl, Coach Kleats, Chunk, "girl with the mole" (traditional find-it BG character for Fernando Ruiz)
Row 5:  Midge Klump, Bingo Wilkin, Alexander Cabot III, Bippy the Hippie (or possibly, the JOSIE version of Clyde Diddit), Fernando Ruiz


ON THE RIGHT of Lawyer
Front Row: Veronica Lodge & Marcy McDermott
Row 2:  Archie, Mr. & Mrs. Lodge, Smithers
Row 3:  (? - bald man w/glasses), Jason & Cheryl Blossom, Gaston (Lodge family chef)
Row 4:  (? - blonde girl w/glasses), Josie(?) partly obscured by Mr. Lodge's head, (? - brown-haired freckled girl), Chuck Clayton, Nancy Woods

NOTE:  Hair color is kind of important in trying to identify a character in a crowd scene from a single image, so if the colorist was off on matching any of the more obscure characters' hair colors to the way it normally appeared in their earlier appearances in Archie Comics, then I probably mis-identified that character.

Not entirely sure on who the lawyer in the center is, but I'll take a guess. It's either Robert Ingersoll (legal columnist for The Comics Buyer's Guide) or Batton Lash.
