The answer is no.
While you can add as many Camera devices to the same email account as you'd like, you can only watch the live session of one Camera device on one smartphone/tablet Viewer device at a time. If you'd like to watch multiple live feeds simultaneously, please use Alfred's WebViewer on your PC.
Additionally, you can set up Viewer Priority so that you can choose which account in your Trust Circle has the final say when it comes to watching live on your Camera devices.
