The batman logo is simple. Here you go. The others, not so much. Those were made using a template. Once you save it all the layers save a single object. That means the logo can't be "taken apart" so to speak. It's possible to erase around the logo but it will look like hell and nothing can be done about the "glossy spot" that will be left covering part of what's left. My advice is send Justafan a PM and see if he still has the original logo. That looks like his work.
