There are various, sometimes very complex structures in hell. For example, a hierarchy where Lucifer Morningstar is on top, and of course many other things worth mentioning. For example, a kind of mechanical construct where female demons can become pregnant for money, in order to have a child that is then trained as a warrior. These constructs are called PLFs. However, hell is a crazy complicated construct, even with infrastructure and other important things that are vital to the maintenance of hell.
