Animating prefabs from blender with multiple objects

I am extremely new to Unity and still trying to learn so I hope I don't look too dumb here. I've Imported an FBX from blender with 8 objects and each has their own animation all in one prefab. I just want to know if this is possible to animate or if I am headed down the wrong path. Here is a visual example.

Ive created an animator controller for each object but they do not work. If I put the animator controller on the prefab in only uses 1 animation. I've looked everywhere but I can't seem to figure this out. Any small insight would be helpful.
