Youngest is Lazy. She's just out of bootcamp.
Then it's probably Wyll. Then Karlach. Then Gale.
Shart is about 50 years old, she was kidnapped 40 years ago and was 12ish when she was kidnapped.
Then Jaheira who is old for a half-elf.
Minsc is middle aged, but was frozen for over 100 years so however you want to count that.
And then we have Astarion and Minthara who are both 250+ years old.
