Sine this is an in-game team I'll suggest moves, but I won't go into natures/IVs/EVs unless you say to later ^^ You've chosen some of my favourite Pokemon btw, well done ;D
Torterra
Use it as a tank, go for an offensive move-set with some healing. I'd recommend Earthquake, Wood Hammer, Synthesis and Stone Edge/Leach Seed depending on your preference...
Floatzel
Really you have two choices here. You could take advantage of its ability with rain dance or you can bulk it up before attacking. Either way, its attacking moves should be Waterfall, Ice Punch and Return, then the 4th move should be either Rain Dance or Bulk Up depending on if you want it fast or strong ^^
Togekiss
LOVEE <3 Basically for Togekiss you'll want to run a bulky special set. Give it Nasty Plot, Aura Sphere and Air Slash for definite. Then Roost would be a good final move to finish this set to compliment Togekiss' natural bulk. Basically you'd power up till you're low on health, heal it with roost then go to town on them. ^^
Mamoswine
Another love of mine here. It's a strong physical attacker with bulk and speed, what could be better? Move wise, I'd suggest Earthquake, Ice Shard and Stone Edge. As far as the last move goes, I'd recommend Superpower, however this may be too hard to get to use in an in game team (especially since you get it post-league) so I'd suggest either Avalanche or Endeavor, depending on your fighting style.
For the last 2 Pokemon, my suggestion would be Scizor and Drapion. It'd be an interesting team that way, however Garchomp would make it very strong. It depends if you want an easy game or not, if you do then go for Scizor and Garchomp, if not go for Scizor and Drapion. ^^ Basically Scizor would run an offensive set (swords dance would help), Drapion would do the same but with worse coverage than Scizor (but it looks way cooler!) and Garchomp... Well, Garchomp just kills everything, I'm not sure you need advice on this one since it's so powerful haha. One thing I would say about your team is watch out for ice types, you seem to have a lot of weaknesses to them and not all that much to combat it :3 Candice and the area surrounding her could give you some trouble. Scizor's Bullet Punch would be a great counter for these.
