A user group bundles administrators, for example your translators or one department. With a group you add all its members to a survey in one step, write one email to all of them, or show a sidebar icon to them only. A user group has no permissions of its own: its members keep their own global permissions and get survey permissions per survey.
Click Configuration > Users > User groups in the top bar.
Click Add user group (1).

Choose an administrator under Please choose... (2) and click Add user (3). Repeat for each member.

The list offers the other administrators of your site. To add someone new, create the administrator first. See Manage administrators.
Open the survey, go to Survey permissions, pick the group under User group and click Add group users. Every current member is added to the survey as a user, and you tick their permissions there. See Survey permissions.
Note: Add group users adds the people who are members at that moment. Someone who joins the group later is not added to the survey: add them in Survey permissions too.
Click Mail to all members (1) on the page of the group, or Email user group in its ... menu, to write one email to every member.
No. Members keep their own global permissions. A group only makes it faster to add all members to a survey in Survey permissions.
A user role is a saved set of global permissions that you assign to administrators. A user group is a list of people you add to surveys, email or show sidebar icons to. See Reuse permissions with user roles.
