... Who is still in play elsewhere, please? ...
NPC wise, Limpy and Daryl are with the party.
Theo and Phil are being held captive with the people Daryl just escaped from, the party is on its way to rescue them as we speak. It is assumed that the mayor's daughter is also there, but Daryl did not see her.
The PCs sent people to go find Olaf and his brother Christian, and ask them to come help you, but they are on the other side of the valley and Olaf indicated that he does not come over this side and is not popular here. They are currently 'safe', so far as the party knows.

... convincing other PCs about something calls for a Persuasion roll ...
There is no mechanism for convincing PCs with rolls, you --the player-- have to convince the
players first and that is not a 'games rules' thing (it is a meta-game thing, technically, but that definition is muddied and sullied). Once the players agree, you can play out the in-game interactions to convince the Player's Characters if needed, if all the players involved want to introduce some randomness we can work out a roll, but that is not common for PCs.
Convincing an NPC could be some sort of roll, but 'persuade' is not a thing, you have to do it in the fiction first, and then we will decide if a roll is called for and what Attribute that is done with, this is often +CHA, but could also be +INT if you are relying on 'reasoned arguments with rational people' or +STR if you are threatening dominance, and so on.
What, if anything, are you actually trying to do?
