They call them "ports" usually. Such things exist for a long time in a
server world, but are infrequent in consumer one.

Yes, it's definitely possible - from IP stack point of view each port is
a different network interface.
It'll unlikely be efficient (compared to a managed switch, that is) if
your plan is to use such card as a router - after all you'll need to
copy all the packets to the kernel and back, and that takes time.
But it still going to beat more common DIY combo of two/three USB-Ethernets.
