OOC: Fufufuu. I can't help myself.
Poison (Female) @ Blackglasses
Timid
Crunch, Iron Tail, Flamethrower, Poison Fang (You know, I really wish it were Sludge Bomb XD)
Mebbe Replace Iron Tail with Earthquake if you still have a TM for that. Also, you might want to replace Blackglasses with Lefties or Scope Lens and give it Haze or Glare instead of Crunch (Fallarbror Move Tutor can do that for one Heart Scale per move).
Volcan (Male) @ Focus Band
Bashful
Thunderpunch, Sky Uppercut, Flamethrower, Bulk Up
I'd say replace Thunderpunch (Which is rather weak) with Rock Slide to make use of Blaziken's high attack. You could also replace Flamethrower with Overheat, combined with White Herb as a held item for some major damaging potential. Also, Bulk Up will probably not bring very much benefit since Blaziken is more of a sweeper, so I'd go with Swords Dance instead.
Minion (Male) @ Magnet LOL!! (Soul Dew is the ideal, but Lefties or Scope Lens are better than Magnet)
Sassy
Psychic, Dragon Claw, Ice Beam, Thunderbolt
This moveset is actually good. But it would probably be better to have Soul Dew (If you can get it) or Lefties for a held item. Also, Recover or Calm Mind are also useful moves which could be used to make it less vulnerable against Mirror Coaters (Milotic is the worst). But with this set, Choice Band could also be a good item (+50% damage) but it would probably bring about a lot of switching.
Magma (Female) @ Quick Claw
Serious
Rock Slide, EQ, Fire Blast, Explosion
Fire Blast is one of the worst moves in the game, so I'd say replace that with Flamethrower (More Reliable) or Overheat (Stronger).
Fishy (Male) @ Scope Lens
Relaxed
Ice Beam, Surf, EQ, Hydro Pump
Hydro Pump sucks just as bad as Fire Blast. Maybe put in Rock Slide for a more varied moveset or Counter for a bit of defensive potential.
Kippy (Male) @ Lefties
Impish (Go Defense! Wh00t!)
Body Slam (Don't ask XD), Ice Beam, EQ, Hydro Pump
Body Slam is quite nice actually. ^_^ But I'd say remove Hydro Pump and Ice Beam, since the Impish nature is going to make Kippy's Sp.Attack really weak, and put in Rock Slide and some nifty support move. Maybe Attract, Toxic, or Rest.
