Valjean: he’d probably try to stay out of the conflict, but he’d be rooting for Robb. After the RW, Dany.
Javert: swears fealty to Stannis and worships him. Very suspicious about both Davos and Melisandre, tho.
Marius: dislikes all current kings, fanboys over Aegon the Conqueror
Enjolras and the Amis: want to overthrow monarchy
Thénardiers: Joffrey. After him, Tommen, to suck up to Cersei. Thénardier is also BFFs with Walder Frey.
The Patron-Minette: Balon. They like how the Ironborn think. When Euron becomes king, they are even more enthusiastic.
Gavroche: none, although he thinks Robb and Renly are okay people. He’d probably befriend Tyrion.
Éponine: fangirls over Renly. After the shadowbaby incident, she finds out about R+L=J and supports Jon.
Monsieur Gillenormand: a Targ loyalist but grows impatient when Dany gets stuck in Meereen, so he’s overjoyed when fAegon shows up and join him.
Grantaire *walks up to Jon Connington* *knowing look* So, you too, huh?
