If you are talking about vms limit on free ESXI 5.5 Hypervisor ..then no issue you can create 3 or more VMS according to your hosts physical resources.
Thanks

If you're talking about physical servers then no, but you're missing out on centralized management, vMotion, load balancing etc, etc. If you can afford it you'd be better off purchasing vSphere Essentials or Essentials Plus which would be perfect for you. (3x Physical hosts + Centralized management)
