I never really used more than the partner, because I always found everyone else worthless resource hogs.
Mystery Dungeon game series have always been built around solo, and while having a second character works well enough, going over that really shows the limitation of the genre as they waste precious turns just getting in position to actually do anything which often is enough to end the fight, can't do shit in hallways, tend to break off from the party and get lost if you aren't careful and eat through your precious Reviver Seeds despite not being an essential party member like your partner so you'll always get fucked over when you need it most.
They don't even over benefits like letting you carry more items, just being an extra body to aggro in case of a monster house but then see above.
