These are files that you created (not yet committed to git).

If you check gitlab, these files are not there.

The file ending with ~ is created by gedit, don't use gedit, use sublime text for programing, we don't need our code base polluted by backup files like these.

Other 2 files in migrations folder is created by "php artisan migrate:make" command.

You can delete those 2 files, make sure you only delete the files (verify name) that listed as Untracked files.
