Early build concepts, any suggestions?

Enjoying the game so far, still in the first town, finally have a group of six I mostly like, and I have a vague concept of what I want to do with them but wanted to sanity-check the ideas/solicit ideas on how to chase those builds.

Protag - Swashbuckler-style Dex/Cha evasion tank. So far have a level of Scaled fist and two levels of the Fey version of Rogue, probably going to grab one more Rogue level, one level of Vivisector and most or all of the rest in Eldristch Scion. This one I think I have pretty much sovled.

Camillia- Want to do a a controller glaive/reach build with her while still preserving a little of her gishy flavor. Is this viable or am I trying to put a square peg into a round hole?

Wenduag- Like her as a ranged combatant, so far I've got her with one level each in Fighter, Rowdy, and Vivisectionist but not super sure how to proceed. Shooting for a snipery feel if possible, but while I know how to more-or-less build that in 3.5, I don't know Pathfinder quite as well. I'm guessing mostly sticking to Fighter is the move?

Ember- Just got her, Witch seems like a good debuffer class and I think that's what I'd mostly like her to do, possibly with some battlefied control. Any must-have dips to pull that off?

Seela- Tankadin. Just keep taking Paladin levels or are there some must-have dips?

Nunio- Seems like she'd make a fun blaster. Again, if it were 3.5 I'd know exactly how to do that, but sometimes those differences can be finicky. What are the fun blaster casters in PF?

I do have a mod to allow respeccing if necessary, but I'd rather only do that if I've already borked somebody's build rather than just because I can.
