You can not use these. Only a few of them are not really custom avatars. I will edit the post with the hidden ones. All custom avatars have to be uploaded individually by Zarel. This is why not everyone has a custom avatar available to them. To get a custom avatar you require to be global driver (%) or higher on the simulator or by being a contributor.
I will list the hidden avatars in the main post.
