Yes, with TUN networking this works fine. Have used this in

  - bridged including the host interface, giving each QEMU a static ip on 
the LAN.

  - non-bridged, routing via the host, with masquerade firewall rules on 
the host to allow traffic to the LAN. Each qemu in a separate network to 
simplify the host side.

  - vde, routing via the host, with masquerade firewall rules on the host 
for allowing traffic to the LAN. All the qemu instances in the same 
network (but different host addresses).

  - bridged, not including the host interface. Same as vde.

All this is with only one network interface on the host.

Note: when using tun, each qemu instance gets it's own virtual tun/tap 
interface on the host.

Note2: The vde based setup is generally the simplest to get correct.
