Yes, you can each use a 9 o'clock travelpass. Al multipack contains 6 of them, so enough for 3 days. Just make sure you don't buy personalized passes. They may ask for your name if you buy them online, but not at the station service desk or ticketing machine.
Please note that you only need such travel passes if you plan to travel a lot in one day. Even a long trip like Basel to St. Moritz, for example, is cheaper with a discounted point to point ticket than with a one day travelpass.
