I think a little different. Since Faris is the unit that I will be "lending" people I would put the best sphere I could on that unit so that I can be of help to other people. Here is what I would do:

Faris kinda wants your best sphere too because she is Oracle. She wouldn't really want the Frozen Myth either because that would boost her Rec to unhealthily high levels.

Arius works well with Leomurg because that boosts his survivability (which he needs desperately as and Oracle) + gives him BCs when he normal attacks which gives him SBB faster for the heal. Dandelga is an OK alternative but I would rather Leomurg.

Exvehl needs the Drevas to prevent himself from being Cursed or Paralyzed.

Ardin can make do with either Frozen Myth or Providence Ring but since Faris would like Providence Ring I would stick the Frozen Myth on him. It fits a little too since you have and Anima which would boost his Def and Rec to really respectable levels.

Luther is the last priority in your squad which might clash with my praising him over Zellha thing. But he could make do with the leftovers that no one wants since his main purpose is to put the spark buff on and help the others spark. His 28 SBB isn't there for his own DMG its there to augment the other units' DMG along with his spark buff.

TL;DR

Faris: Legwand > Providence Ring > Frozen Myth > Medulla > Sacred Jewel

Arius: Leomurg > Dandelga

Exvehl: Drevas, don't want your anti-status to get statused

Ardin: Legwand > Frozen Myth > Providence Ring > Medulla > Sacred Jewel

Luther: Legwand > Medulla > Sacred Jewel (leftovers)
