5. By age, who is your youngest char­ac­ter? Old­est? How about “youngest” and “old­est” in terms of when you cre­ated them?

Let's see...my youngest character is Jennifer in Terminal Dreams. She's 14 and is the one that first suspects her older sister is haunting the house. She also gets in touch with the ghost hunting teams. I think my oldest character is Nikolas in The Last Days of the Unreal City. He's in his 60s and works with a group on Earth trying to rebuild the ground cities after the war.
In terms of age of creations, Liera in my as untitled NaNoWriMo 2011 is actually the oldest. I created her way back in middle school, and the story has gone through so many permutations in my head. This year is when I hope to really write down the story the way I want it. Youngest in terms of creation are the cast of The Last Days of the Unreal City. I made them all up last year for NaNoWriMo 2010.
