After creating a page, you can scroll down and find Page Options. You can set the page option which priority to display of only this page in front-end.
For example:
If the default header is Header type 1 but you choose Header type 3 in Page Option >> Header >> Header Type then Header Type 3 displays in your page instead of Header Type 1.
You can choose the option in General, Color, Background, Header, Title, SideBar, Slider and Footer.
