Who hosted the different shows. I'd really like to know!

All I know is Mark Walberg hosted Friend or Foe.

Mark L. Walberg - Friend or Foe
Kennedy - Wintuition
Graham Elwood - Whammy
Todd Newton - Russian Roulette

Chuck Woolery still hosted Lingo, but the contestants were the GSN hosts. Mark & Marc vs. Kennedy & Graham. Todd was Chuck's announcer and sidekick.
