How can I hide calendars from Siri? When I open the Calendar app, I have some hidden calendars which I don't normally want to see.

Short answer: No. 

No, at this moment it is not possible to hide calendars from Siri. I highly recommend you send this feedback to Apple. 

A workaround would be to use a second calendar app to show the calendars of your family and use the normal calendar app only for your own calendars.
