Shounl be not that hard to make.

Create different sprite and animation for each direction. Then in anim BP switch them depending on direction and camera vector difference.
To know how to do this, you should watch tutorials. Follow one about setting up character in unreal.
When you know how to setup 3d character, you need to find out how to make 2d character in 3d space. Probably some flat meshes and material that can be animated.
Or use 2d skeleton but i am unsure if that can be used in 3d,
