Does "group" refer to sudo users where they must specify a password in order to access/modify it?

"group" in that context refers to the specific group assigned to that file or directory. If you use ls -lh instead of plain ls you can see which group is referred to.

If you use id or groups you can see which groups your account is a member of. You can then assign any of those groups to a file or directory you own using chgrp.

Groups are just user groups, allowing users to share specific information, part of that group. If group permissions are set, i.e. if chmod g+r or w or x, then the group has access. No password needed nor any other prompts.

A 'group' allows members of that group access to all files owned by it, useful for collaboration.

There are a number of groups on a Linux machine, & you can create your own, & add who you want to it.
