Wikipedia says they have 4 Crew Dragons in service, 1 under construction. - Crew 8 is docked at ISS - Polaris Dawn is on the launch pad scheduled for Monday. It is configured for a space walk, so I think that means it doesn't have the ISS docking adapter installed - Crew 9 is launching in September (with 2 or 4 astronauts) - Fram2 mission is in December. I think it is going to have the viewing cupola installed, so no port

I don't know how fast a Dragon could be refitted with the docking adapter so maybe the other 2 aren't available on any sort of emergency basis.

The emergency plan for Butch and Suni until Crew 9 gets there is either YOLO Starliner or lay on the bulkhead of Crew 8 below the 4 astronaut seats, not wearing space suits since the Starliner suits can't be hooked up to Dragon.
