You can do it with a router, just tell it not to allow any traffic between
the 5 segments. Any router worth it's salt can do it.

5 cards in one box might be awkward due to IRQ etc, but there are 4-port
ethernet cards on the market, some of which support linux. I've heard good
things about www.znyx.com on this list, so you might want to try them.
I think by default the linux kernel can handle 32 eth? devices, so you
should be ok there... :-)
A router is likely to be more cost effective, but a linux box with a couple
of 4-port cards is going to be more flexible, as it could also run various
services, firewall, even be a file/print server...
