Yes.
normally port based vlans are for switch based ports linked to individual
end devices.
Tagged portsused to connect devices which handle multiple VLANs - often
other switches

without know the device involved then you are basically asking for educated

Depends on the switch implementation - there is no reason that
"membership of multiple internal vlans" must map to
"tag the packets with the internal vlans on this port"
- but it may do.
you may need to set the port into "tag" mode explicitly.

If the port is set for vlan tagging, then it should use it for both inbound
and outbound packets.
