Multiple meshes overlapping eachother

Hello, I was creating a character and accidentally duplicated a lot and only now noticed, how can i delete the extra meshes / armatures without affecting the original armature and model while being efficient?

Press X

Make sure to keep at least 1 mesh deselected, Don’t want to delete the head mesh itself!
