Tyrion promises Brown Ben Plumm of the free company The Second Sons lots of gold in return for the right to join up and, presumably, have some influence in what they do, though this is not clear. He's given a job helping Inkpots, aka Tybero Istarion, the treasurer, to manage the funds. He had this job in King's Landing and was good at it, I seem to remember. Plumm plans to stick around until Meereen is taken and then head to Westeros.
Penny is annoyed with Tyrion about abandoning the pig and the dog. Escaping slavery is not the end of her problems, either. Maybe one day Tyrion will regain some power, or else find some quiet life in a cottage somewhere, and can give Penny a comfortable life. Because that's how things work out in GRRM stories...
Jorah Mormont is still with them too and will probably make a good sellsword. He notices that the Yunkai'i, who plan to attack Meereen, are unlikely to win if Dany returns with her dragon. Tyrion thinks he can get them to switch sides.
