May I have some opinions and advice on my team?

I currently made a new paladin and I am loving the class so far. But as for my team, I've been wanting some feedback as to what I should enhance and what to replace if needed. Current Team:

Lvl 72 Paladin

Lvl 83 Dmitri +5

Lvl 83 Shabelle +4,

Lvl 83 Queen Caberra MAX

Lvl 83 Captain Fulson +2

In my inventory, I currently have: Deathcrown, Mara, Dark Swordsman Pagu, Spark Wizard Ann, Commander Abunarq, and a whole bunch of other SS's. I've been stuck on the Infernal Fortress stage of the second chapter and was wondering what I should do with my team. Any advice?
