What you are asking is, Can a Bluetooth device do multiple pairings? There is no general answer. Some can and most can't. Those that can usually do so sequentially, not simultaneously.

For complete details Google multiple Bluetooth pairings.

Devices support pairing with multiple sources, but they can only stream from one at a time. Activating a second audio stream stops the first. This is unavoidable.
