Help with page navigation

Hi, complete noob here, i cant seem to find an answer, so excuse me if this has been answered before.

I’ve downloaded multiple plugins for page navigation, but it seems none of them are working…or maybe i’m using the wrong ones.

anyway this is what my pages look like..

I’m wanting to just create a “next page” “previous page” and “Home page” where it will take you back to the first page.

Any help will be much appreciated, and again i am an absolute beginner when it comes to coding, all of that is a blur to me.

Thanks in advance!
