Need help with Movesets, rate my Team please!

Hello! Im new to competitive battling, and I was wondering if I could get some assistance with my Wifi Teams Movesets? I also want help with what item they should hold.

Torterra @No Item
Gentle Nature

Frenzy Plant
Synthesis
Crunch
Earthquake

I want to keep earthquake because its powerful, hits most of the time, has STAB, and my Torterra has good Physical attack. I was thinking of teaching him Stealth Rock.

Arceus @No Item
Naughty

Judgement (A Must have)
Thunderbolt
Extremespeed
Hyper Voice

This is where Im having trouble with movesets. I don't want to give it a plate of a type that I already have.

Regice @Nevermeltice
Bold

Hammer Arm
Zap Cannon
Superpower
Ice Beam

I want him to be my Defensive wall, because its Defense is pretty good, and his SP. D is CRAZY!! (414). I don't want him to know alot of Physical attack moves because its...not so great. The only attack I plan on him keeping is Ice Beam, because the rest either have low accuracy, or lower his stats.

Luxray @No Item
Quirky

Crunch
Swagger
Charge
Thunderbolt

I hate this moveset. I like Crunch, and Thunderbolt. But I don't ever use swagger. Raising the attack of your opponent for confusion worth it.

Darkrai @No Item
Quirky

Psychic
Dark Void
Dark Pulse
Shadow Ball

Don't really have many comments. I don't want to add Dream Eater because thats way to expected of Darkrai to have.

So...please rate it, and any reccomendations for movesets will be appreciated.
