Cecil should attack the soldiers. If he kills them first, the officer will run. If he kills the officer, the soldiers will kill themselves, at least I think so. They might only kill themselves if there is only one soldier left.
ATTACKS: Officer ordering soldiers to attack.
Have Kain jump and Cecil attack. When it turns into Mist, don't attack or it will use a more powerful attack against you.
ATTACKS: Regular Attacking, ColdMist.
Rydia and Tellah should use Lit, and Cecil should attack. After a while, Octomamm will die.
ATTACKS: Regular Attacking
Have Rydia keep summoning Chocobo. If Cecil or Edward attack, Antlion will Counter. You should be able to beat it with just Rydia.
ATTACKS: Regular Attacking, Counter
Have Yang use his regular attack, Cecil should also attack, and so should Edward. Rosa should heal and Rydia should summon Chocobo. After a while, it will probably explode on all of your party members, and turn into 6 regular bombs. Direct all of your attacks at one of the bombs; trying to spread out your attacks takes too much time, and you must act fast. If you aren't fast enough, each bomb will explode on a party member, and that person will almost certainly die.
ATTACKS: Regular Attacking, Explode
In each fight, all you have to do is fight. Use Cures when neccesary.
ATTACKS: Regular Attacking, General ordering other enemies to Charge.
Have Palom and Porom use Twin every chance you get. Cecil should direct all his attacks at Milon, because attacking the other monsters will only do one point of damage each time. Tellah should cast Fire and heal the party.
ATTACKS: Regular Attacking, Lit 1, Revenants use Drain
He will attack you from behind, so be prepared. As always, Cecil should fight and Palom/Porom should cast Twin. Tellah should cast Cure 2 on Milon; since Milon is undead, Cure will hurt him.
ATTACKS: Regular Attacks and he will poison you.
Don't fight. Don't even heal. Parry each turn. The battle will end eventually.
ATTACKS: Dark Wave
You shouldn't have problems with the Guards, so I won't tell you how to beat them. Have Cecil fight and Tellah and Palom use black magic. Porom should heal. After a while, Yang will regain his senses.
ATTACKS: Regular Attacking, Kicking all party members.
Do NOT use black or white magic on Baigan's head/body. He'l cast wall on himself, reflecting your magic. He won't cast wall if you use Twin, though. *HINT* Tellah should heal and Cecil and Yang should fight Baigan's head/body. When that part is gone, kill his arms.
ATTACKS: Fast (on himself), Regular Attacking, Wall (on himself), Recover (on his arms), Fast (on his arms), and his arms use Vampire.
Have Tellah and Palom use their strongest Lit spells, no matter what form he is in. Porom should heal and Cecil and Yang should fight. When he hides in his shell, he will heal himself. He doesn't heal a whole lot of damage, so he'll be gone in no time.
ATTACKS: Regular Attacking, Wave, Remedy (on himself), Ice2
It doesn't matter what you do at first. He will kill all or most of you. When Edward plays his harp, you will be fully healed. Cecil, Yang, amd Cid should fight. When Dark Elf changes forms, have Tellah cast weak. Then have someone attack to kill him.
ATTACKS: The three level 2 elemental spells, Regular Attacking
