The first and second fellow are both based on actual people from history. The first, Taillefer. The second, Twisty Pole. The third fellow isn't based on anyone in particular, though with that hair of his he's likely an ancestor of Ruby's.
I wanted to try to make the backgrounds behind Taillefer and Twisty Pole reflect their time period / location if I could. The first section of background is from the Bayeux Tapestry. The second section is a recreation of this painting. References are your friends. Use them.
