Sadly no as none of them have been enabled for multiplayer.
I'm not certain that even if they were available, they would be of much use as I don't think you can save them in your game. DS1 was designed that way I believe. Even if they were enabled in the map, you would have to rehire them ever game session.
I may be wrong, in which case I'm sure somebody will respond with a more informative answer.
