Duplicate Page Template

I’ve searching for help to how to duplicate a page template in Evolve Theme and everything point to child-theme and Css editing. I know how to create a child theme and edit the css style in the child theme; I have no problem with that at all.
Again, how can I duplicate a page template so I can have different graphic content and layouts in each different page using the same widgets? This is simple straight forward question; I would appreciate a simple straight forward answer. I already have the child theme crated and I already have edit some of the style, please don’t ask for my URL because I running this in a localhost.
