Changing links to pages on my Navbar in the Template

Hello there,
Thanks to all those who’ve helped me answer questions before. In building my site (I’m still a newbie) I purchased a template and on the Navbar and top menu, there are prefigured links, i.e. about, contact, photography (which I want to turn into the topic of culture) etc. Being that the links I want are kind of attached to buttons in the wrong place, either wrong menu or wrong side of things, I was wondering, how do I keep the pages but link them to different options in my menu and navbar? Is that even possible? Thanks!
