Deleting "/header/", "/untitled/", "/hello-world/" pages

Hello, Yesterday I added the website link (examplelink.com/) to the google search engine and now in the google search are pages (from bellow) higher in search results than the default page. I am using a static front page and this is the only page on the website.

The default page link does not have any extensions: xamplelink.com/

I would like to delete those pages:
examplelink.com/header/ (this page exists, but I can’t see this page under the dashboard - > pages…)

examplelink.com/untitled/ (this page can be found by google search, but don’t exist under the dashboard -> pages.)

examplelink.com/hello-world/ (this page can be found by google search, but don’t exist under the dashboard -> pages.)

Thank you.

Hello there,

I hope you are doing well today.

Your hosting provider may be caching the page so you would have to clear your hosting cache if that feature is available.

On your end you can clear your WordPress cache using the following plugin:
