You can typically put more than one untagged VLAN on a switch port,
but like Micheal said you don't want to.

The configuration process for cheap switches is usually two fold, only
put the VLAN you want to use on the port, untagged, and set the PVID
or native VLAN depending on the terminology of the switch, to whatever
VLAN you're using.
