To the Dungeons with Ya

[Sreaction]

After having defeated the Vaegirs, I have King Yaroglek and a number of other captured lords in my town prison/s. I have good relations with some of them and wouldn't mind recruiting them into my Kingdom. However, there isn't anyone who will ransom them so... Its a life sentence. Seems a bit harsh

 

[Lord Brutus]

They will escape eventually, it just takes time.  If you're playing Diplomacy mod your constable will have the option to release prisoners.  Release the ones you want to recruit.

I am playing vanilla so no constable for me.

Go into the dungeon and talk to them, should be able to free them. Although this could be a diplomacy addition too, not sure. Worth a try.
