If you look at the feet of the place holders they have little coloured blocks these state their class.
There is one Cleric, White. Two Fighters, Blue. A Bard, Pink and a Rogue, Red.
I don't know if this will help later or ever but at the least it's more trivia to add to the pile.

Bard? Or Band? :D Either way, they'd better be tough sorts if they expect to survive for any length of time in Cafe Gruesome! ;)
