What to do with extra pages in Premium template?

I purchased a template from themeforest for my membership site project. It's like a landing page sorta template and has lots of different pages (styles examples) that you can select from. I don't want to delete the pages because I may need them later. So, do I unpublish those example pages or just noindex/nofollow them if I don't want the search engines to spider?

TIA
