You can definitely give other users and groups unique privileges.
Posix ACLs only allow each unique user/group to have 3 permissions read / write
i.e. the normal UNIX permissions, but expanded to have the ability to define
them for multiple users and groups.
So what you describe should be possible.
NTFS also has a delete ACL I think that is not supported, and I don't know how
Modify and List Folder Contents are handled.
