Can you help me fix the errors?

Please help me understand what these errors are: where they come from, how they are solved correctly

Answer 1

Most likely, you are trying to push to someone else's remote repository. This is not how it is done in github, first you fork the repository, then make changes to your local fork, and then create a pull request, which is approved or rejected by the owner of the remote repository (or other participants with write access, which are appointed by the owner).
