WordPress, by itself, doesn’t have that many settings to deal tweak — so it might be easier to simply re-do the settings on the new server.
If by “settings” you meant your posts/pages/content, use the built-in Export/Import function — export from the old server, and import the exported file into the new server.
If you’re talking about the settings of a particular plugin or theme, that will depend on the specific plugin or theme: some have export/import functions, some don’t.
Finally, you can use any of the cloning plugins to make a complete clone / duplicate of a WordPress site (eg when transferring a WordPress installation from one server to another, or from development to live server). My favorite is Duplicator (https://wordpress.org/plugins/duplicator/), but there are a whole lot of them in the plugins repository.
PS: I can see you’ve asked a bunch of other questions, but most have gone unanswered. It might help if you try to clarify your question as much as possible, as we’re all volunteers here and most people don’t have the time to consider all the possible interpretations of a vague question.
