Blender Keyframe animations

Need animations cloned to match existing models exactly. Have 2 different rigged models, see pictures. Three.js knowledge is a plus. I included the 3d model with the animation that needs to be made for the 2 characters. I also need an adjustment to the current rigs. Need joints renamed to attached sound.

1. Rename 4 joints in Rigs.
2. Make animations for 2 rigged models
