Can I have multi superusers and add them to $conf[’superuser’] = line in local.php?
I don't think so. Best to create the superuser group and use $conf[’superuser’] = "@admin".
How do I create a group and put users in here, and set ACL so they can read edit upload etc?
See
http://wiki.splitbrain.org/wiki:acl. When you add the user through the user manager, name the new group there and then the new group is created.
Hope that helps.
