Before moves I must ask: Why three flying types on one team, all of which are vulnerable to ice? And two who are x4 to it? Anyways, I won't rip on Pokemon choices.
Here is my input, feel free to rip it apart. Is it in-game or competitive? Consider reading Plapti's ever so handy Guide to A Competitive Team.
Salamence
Adamant/Jolly
Dragon Claw (STAB)
Aerial Ace (STAB, never misses)
Flamethrower/Fire Fang/Brick Break (for Ice types)
Dragon Dance (+ Attack and Speed)
Blaziken @ Shell Bell
Adamant/Jolly
Blaze Kick/Fire Punch/Flare Blitz (STAB though Flare Bliitz causes recoil damage)
Sky Uppercut/Brick Break (STAB)
Night Slash (psychics)
Rock Slide/Stone Edge (flyings)
Lapras
Modest/Brave
Surf/Water Pulse (STAB, Special)/Waterfall (Physical)
Ice Beam (Special)/Avalanche(Physical, hence Brave nature)
Psychic/Thunderbolt/Body Slam/Perish Song
Psychci/Thunderbolt/Body Slam/Perish Song
(Sorry, not much help for the two other moves >
