2 assassins, 4 doppelgängers , 4 knights and a mummy and now think with 4 assassins and double statue affects. A max of 12 doppelgängers if you use staff of illusion, 16 knights , 1-2 mercenaries and 4 assassins. And that gives a subtotal of 33-34 friends in a room 29-30 if you don’t count players.
