Please note that my suggestions are very loose and missing ALOT of detail. You didn't have any of the other details, however, so I guess you don't mind that. These suggestion are only suggested for the default AI (Which I'm guessing is what you use it for mostly)
Empoleon
-Surf
-Ice Beam
-Flash Cannon
-Hidden Power
Not sure about his set, If hidden power is a different type then your other attacks, use it, otherwise something else.
Dragonite
-Dragon Dance
-Dragon Claw
-Earthquake
-Aqua Tail
Insanely powerful and anything that Dragon Claw and Earthquake don't affect you can use Aqua Tail for.
Typhlosion
-Focus Blast
-Flamethrower
-Earthquake
-Rock Slide/ Hidden Power?
Not a good set, but Typhlosion really has limited options. Honestly, whatever you prefer is good over earthquake and rockslide, like hidden power, or I guess solarbeam is ok for normal AI trainers.
Tyranitar
-Stone Edge
-Crunch
-Rock Polish/Aerial Ace?
-Earthquake
Tyranitar is slow so Rock Polish could really help at the start of the battle, unless you plan on switching him out, aerial ace helps with fighting types.
Magnezone
-Mirror Coat/ Thunderwave
-Thunderbolt
-Flash Cannon
-Volt Switch/ Hidden Power
Rather limited movepool, but its not too bad. Mirror coat is useful for fast SpA users, thunderwave is to slow a pokemon then dish out the hurt. Volt Switch can be used as more of a scout role (Even though hes slow), but hidden power could provide coverage.
Chandelure
-Flamethrower
-Energy Ball
-Shadow Ball
-Psychic
Good as a Special Attacker, you could make use of Calm Mind in there to boost his attacks, but its not necessary for the most part.
Again, you didn't provide me with a broad spectrum to interpret, but thats not a huge deal if your in it just for the fun
