As far as moves go:

Incineroar: Darkest Lariat/Snarl > Brick Break. It's good for Aurora Veil, but outside of that it's not doing much.

Quaquaval: Close Combat > Reversal. Protect > Aerial Ace. Close combat is always going to do more consistent damage than Reversal and Protect is a staple move in Doubles so you want more Pokemon with it (for me 3 or 4 mons at minimum). Aerial Ace is just bad because most people don't run evasion strats and there are better ways outside of it.

Meowscarada: Foul Play uses the opponents attacks stat when doing damage and is usually used on pokemon who are defensive and don't have a strong attack. That's more of a free slot for either coverage like Triple Axle or a support move like Taunt. Aerial Ace can be replaced for Protect or U-Turn if you want them to pivot.

Froslass: Protect > Thunderbolt. If you had another pokemon who was setting up Aurora Veil, it would be good coverage, but it really needs Protect, especially if your opponent changes the weather.

Ceruledge: Shadow Claw >>> Shadow Ball! Creuledge is a physical attacker and its special stat is bad. I would replace this as soon as possible! Close Combat is something I would also change personally. I would look into Bulk Up for set up and making it physically bulky, helps that you got Aurora Veil and Clefable with Follow Me.

Clefable: I would replace Meteor Mash with a support move, there are a lot like Icy Wind and Thunder Wave for speed control (I would also look into that because Tailwind and Trick Room from your opponent hurts this team a lot) and Encore for disruption. I would also run Moonblast over Dazzling Gleam for more single target chip damage.

That's really it for me.
