There's no need to triple-post; all of these could've been one. Natures and EVs are also highly recommended to include, as they're very important in competitive battling.
Anyway, Charizard X is best as a physical attacker because of its Tough Claws ability:
-Dragon Dance
-Flare Blitz
-Dragon Claw/Outrage
-Roost/Earthquake
Nature: Adamant/Jolly
EVs: 252 Atk/4 Def/252 Spe
Item: Charizardite X
Ability: Blaze
Some of your other Pokemon are badly outclassed in the standard environment. Poliwrath and Rhyperior aren't good options because the former doesn't have much to make it stand out from its fellow bulky Water Pokemon like Wash Rotom and the latter has way too many common weaknesses to take advantage of. Starmie is a better fit over Poliwrath because it can use Rapid Spin to clear away entry hazards, as Charizard is weak to Stealth Rock:
-Hydro Pump
-Psyshock/Thunderbolt
-Ice Beam/Hidden Power (Fire)
-Rapid Spin
Nature: Timid
EVs: 252 SAtk/4 SDef/252 Spe
Item: Life Orb/Leftovers
Ability: Natural Cure/Analytic
or
-Scald
-Psyshock/Reflect Type
-Rapid Spin
-Recover
Nature: Timid
EVs: 248 HP/8 Def/252 Spe
Item: Leftovers
Ability: Natural Cure
A better replacement over Rhyperior that doesn't stack too many weaknesses with what you currently have is Garchomp. While it doesn't hit as hard as Rhyperior, Garchomp is noticeably faster, allowing it to make better use of its offensive presence:
-Stealth Rock
-Outrage/Dragon Claw
-Earthquake
-Swords Dance/Fire Blast
Nature: Naive/Jolly
EVs: 252 Atk/4 SAtk/252 Spe
Item: Focus Sash/Lum Berry
Bisharp has no use for Hone Claws, as all its good moves are very accurate and Swords Dance boosts its Attack twice as fast. Night Slash is also outclassed by Knock Off, as the latter has utility in removing non-Mega Stone items:
-Swords Dance/Pursuit
-Sucker Punch
-Iron Head
-Knock Off
Nature: Jolly/Adamant
EVs: 4 HP/252 Atk/252 Spe
Item: Life Orb/Lum Berry/Dread Plate/Black Glasses
Ability: Defiant
Raikou has no use for Extreme Speed, as it's already fast on its own. As the move came from an event a long time ago, it forces Raikou into a Rash nature, which is suboptimal considering that Raikou will now be outsped by Garchomp. Use a Timid nature instead to make use of its good Speed:
-Calm Mind
-Thunderbolt
-Hidden Power (Ice)
-Volt Switch/Substitute
Nature: Timid
EVs: 252 SAtk/4 SDef/252 Spe
Item: Leftovers
or
-Thunderbolt
-Volt Switch
-Hidden Power (Ice)
-Shadow Ball/Extrasensory
Nature: Timid
EVs: 252 SAtk/4 SDef/252 Spe
Item: Choice Specs/Assault Vest
Alakazam is better with Shadow Ball and Focus Blast as its coverage attacks over Dazzling Gleam, as the former two moves have unresisted coverage together:
-Psychic
-Shadow Ball
-Focus Blast
-Encore/Hidden Power (Ice)
Nature: Timid
EVs: 4 HP/252 SAtk/252 Spe
Item: Life Orb
Ability: Magic Guard
