Hi,

For the unused sprite see this post : you'll see the vanilla unused sprites and jobs --> Elric consolidation project

For the formation sprite see this post : Celdia's tutorial
You'll learn how do your formation sprite. Once you do this you can import them with shishi  (under the other image tab, UNIT.BIN formation screen sprite)
