For the sprites listed here, they are;

First row: Alexander Highwind Tycoon, Chancellor, Pirate, Goblin, Green Robed Old Man, Purple Robed Old Man, Dancer, Child Bartz, Stella, Scholar
Second row: King Walse, Walse Soldier, Galuf's World Soldier, Merchant, Queen Karnak, Monster, Abductor, Siren.
Third row: Werewolf, Mid Previa, Cid Previa, Magissa

Some other FFV characters, (besides the ones that are playable) that appear in the Record Keeper story but aren't shown here are Boco, Black Chocobo, Wing Raptor, and Garula as they just reuse there sprites from GBA. Also, I think the Scholar might be missing some frames.

Funny how Siren is just using her sprite from FFV instead of a unique one lol.
