Just individually.  There is a port for ifstated from OpenBSD that
monitors multiple interfaces and will fail a CARP group if one of them
fails.

Although it may have made it into the ports tree by now.

add to rc.conf:
cloned_interfaces="carp0,carp1"

That will create the interfaces, then you can use the normal
ifconfig_carp0="inet 192.168.1.4 ..."
