Answer 1

You can absolutely change the name of the folder without having any problems. If you want to change just the themes name, open the style.css in the root folder of your theme and edit the name in the comments at the top of the file. If you plan on doing more changes, you might be better off creating a child theme: https://codex.wordpress.org/Child_Themes
