you can only have one qjackctl instance running against one X server.

however, being there one possible workaround, you can have multiple
instances, each controlling its own JACK server name  you tell via the
JACK_DEFAULT_SERVER environment variable.

eg. on each terminal, maybe you can have it like this:

  export JACK_DEFAULT_SERVER=<remotehost>
  ssh -X <remotehost> "export DISPLAY=<localhost>:0; qjackctl"
