upload not done right

I uploaded the theme pack and didn't know which theme tab to upload it to but should I have made a new file? I uploaded to a theme I wasn't using anymore. Now when I activate it it just says the original theme name but it's in my FileZilla act under that one theme(all of them). I just can't activate them individually. just the one theme. Do I redo it and if so what is the proper way individual folders or in a new individuale one?How do I give screenshot or links if it's in maintenance mode? Sorry I am so new at this.
