You don't need multiple NICs if it's all going on the same subnet or lan 
segment.  And, no, there is no "balancing" anyway.

You can assign extra alias IP addresses to the one NIC (rc.conf option). 
Then tell apache to only use one, with a "Listen" directive in its 
.conf.  You can also setup Apache to do "virtual hosts", so one Apache 
serves multiple web sites.  Google for that one - there are lots of 
tutorials out there.

The best thing is to probably do is config multiple addresses on the 
NIC, then run each server process in its own jail so they're isolated 
from each other.  There's a good WIkipedia article on FreeBSD jails I 
was reading just yesterday;  it links to a couple good tutorials.
