The enemies in that final sequence are as follows:

The first tier is comprised of Face, Long Arm, and Short Arm.

The second tier is comprised of Hit, Tiger, Tools, and Magic.

The third tier is comprised of Sleep and Girl. It's worth noting that you can steal a Ragnarok (sword) and an Atma Weapon from them, but it doesn't really matter that much since you can't leave with the weapons.

Finally, you fight Kefka himself.

The names of the tier components are accurate, strange though they may seem.
