Hello! I believe I can answer a few of these questions.

The wikifactory group is related to mw:Extension:WikiFactory and allows access to internal wiki configuration.

The restricted-login group is designed to prevent staff members with powerful rights from being able to login via Facebook, or use the forgot password prompt. (I think, anyway.) You may want to look through Special:Listgrouprights.
