can you connect to a separate speaker with music via bluetooth? I already use bluetooth for my music. Can I also connect two devices using bluetooth?

Yes, you can connect to a separate speaker with music via bluetooth.

How do I get a second wireless mic headset for this to use when battery dies on first headset?

The wireless set is unreliable and I was never able to find a replacement. So I went with wired and no more problems.

It says the battery can last up to 2-3 years. But I don’t see any opening on the devise to put new ones. Can the batteries be replaced by the owner?

It is a rechargable battery (in both the headset and the amplifier). If there is a limit on the life of the rechargable battery, I'm not aware of it and I've had no issues with my batteries after far more than 3 years.
