First of all, if you want to have a proper team, then you're going to need the right 5 perfect IVs on each Pokemon, as well as the right nature. For example, your Honchkrow lacks a perfect Attack IV and has a Modest nature, which boosts Special Attack and lower Attack. This is a problem, as Honckhrow is primarily a physical attacker, and your moveset agrees with that. Check the natures page on Serebii if you're unsure of which natures you need. Most attackers have a nature lowering the offensive stat they don't use, and boosting Speed.
Rapidash - It's ability should be Flash Fire, so it can have one immunity that Rapidash can switch into for free, while also powering up its own Fire moves. Flame Body only has a 30% chance of activating, and you won't see Rapidash tanking any physical hits, anyway. Bold nature is really weird, as it lowers physical Attack, which Rapidash needs, and raises Defense, which is mostly futile. Run Jolly, to up that important Speed stat and lower Special Attack. IVs need to be perfect on everything but SpAtk. I understand you have Inferno, but that is a terrible move with 50 accuracy. Consider replacing it with some other Fire type physical STAB, like Flare Blitz. The recoil might be a little troubling, but all physical Fire type attackers need it to deal proper damage. Item shouldn't focus on boosting one type of coverage; put Life Orb. Megahorn and Poison Jab are okay as coverage moves, but consider replacing for Wild Charge, which can allow Rapidash to take on Water types, or Drill Run/Low Kick, for Rock types. Protect is... questionable. It may be handy for scouting out the opponent's moves, but better utility comes in Morning Sun, which recovers HP, or Baton Pass, which acts as a delayed switch so you can choose a Pokemon after seeing if the opponent switched or kept in their Pokemon. Otherwise, you might as well fit a coverage move in that slot.
Espeon - Ability needs to be Magic Bounce, which is far superior to Synchronize. Adamant nature is also really bad, increasing Atk and lowering SpAtk. Get Timid to increase Spd and lower Atk. As a screen setter, EVs should focus on HP and Speed. Since you have Light Clay, you might as well run Dual Screens instead of just one, so put Reflect over Future Sight, which is generally too unreliable. Morning Sun might be alright for sustaining longevity, consider Yawn for a decent utility move that forces switches.
Lucario - Justified is the necessary ability for Mega Lucario, so you can switch Lucario in to get a boost off a Dark type move. Nature says Quick Claw(?), but regardless, you seem to be running physical (since Swords Dance), so use Jolly. Max EVs in Atk and Spd. Swagger is a generally unreliable move to use, and Lucario prefers attacking instead. Replace Flash Cannon and Swagger with Extremespeed/Bullet Punch and some coverage move, like Crunch or Ice Punch, to fully take advantage of any Swords Dance boosts you get.
Dragalge - Absolutely needs Adaptability, which greatly improves power of STAB moves. Rocky Helmet is a waste, Dragalge can be KOed by Earthquake, which doesn't even make activate it anyways. Put Choice Specs for power, or Black Sludge for longevity. Attack should be the imperfect IV. EVs should be in HP and Special Attack, although you can run a certain amount of Speed EVs to outrun certain threats, you can check Smogon spreads for details. Rain Dance and Aqua Tail are wasted slots, replace with STAB Sludge Wave and a coverage move like Focus Blast or Hidden Power Fire, if you're willing to breed for it. Dragon Pulse is an alright move, although Draco Meteor can bring more immediate power to nab some KOs that Pulse can't; this one's up to personal choice.
Honchkrow - Moxie is a fine ability. Change nature to Adamant for proper boost to physical Attack. Item should be Life Orb to secure high damage output. IVs should be excluding Special Attack, not physical. EVs are strange, you don't carry any special attack moves; max Atk and Spd. The moveset is good. Roost can be replaced by Superpower for coverage, but it's not an absolute must.
Gourgeist - Honestly, can't give much advice without knowing which size it is. I can say this much, though - have a nature reducing SpAtk, Bestow+Toxic Orb is a terrible combo that can only work on opponents not holding items (you'd need Trick, and even then, Gourgeist has access to Toxic and Will-o-Wisp anyway to be equivalent to orb Tricking), and make sure IVs exclude SpAtk.
