Just as a response to you and any future buyers. I had bought this pack, and they are poses. Most aren't animations that can be used in action/combat battle system.

The poses are animated. They are simple 3-frame "idle / weapon ready" type animations, as explained in the description.
The animations are to provide additional personality to characters or cutscenes. They can be used in rpg-style battles if wanted but that was never their purpose.
Additional "battle animations" are on the to-do list for a possible future expansion. This is a LOT of characters though so that is not an easy task.
