"There is an enemy in the lowest level that's best defeated by a high-defense character. Robin is the first one who can challenge it, but you can have one of the other groups come back for it later."

As far as I can see, all encounters are only available before the three groups take down the barrier. The only enemy exempt from this is the enemy group outside, where you meet Ginasta.

Also, adding up the xp from the fights in the castle, Riala's group gets the most and Simon's group the least xp.
