LightWithLove I was trying to find a better picture of Will but got distracted by finding stuff for the other three and still haven't found one for him. I also figured that since you're playing Little John, you should know a little more about them.

Aden (Add-in) De' Loughrey
22, born of a noble family, sold to be a servant at the castle at the age of 7 for reasons still unknown to him. He escaped at 17, killing two guards in the process, and joined Robin Hood at 18, He's known Elaine since he was 18 and has been with her since, he's always intended to marry her but has also been afraid that if they were to marry she'd just be in even more danger.

Halig Macleod
26, born in Scotland, his parents brought him over when he was 10, he joined Robin Hood at 20. He doesn't really have a lot of luck with women, though it's unclear why.
His hair is more red/orange than the images.

Rai (Rie) Millar
25, born just a town over from the castle. His father was a guard, and so he followed in his footsteps and became one as well. His father was still a guard when he was, and when he was hung for treason after disobeying orders and not burning down a home with the family inside, Rai left, joining Robin Hood at 21. He's usually a big flirt and does end up in the beds of many women, as Halig said.

And here's Robin himself, I was thinking he'd be 28 (Will is 26):
