You can simulate as many machines as you want, but you may or may not be able to hook them together like you want to. The barrier to simulating more than two machines on a standard network is that there is no Ethernet switch model, just a simple link. So you can hook two machines directly together, or simulate even more machines if one of them has multiple interfaces and acts as a software router (we've done this before, to model the performance of the machine in the middle that's forwarding packets). But if you want a conventional network, you'd have to write a model for a switch. It wouldn't be terrifically hard, but it's not there out of the box.
