LabVIEW PDA does not support having multiple panels (VIs) to be visible at the same time. You can have multiple VIs running at the same time, but only one front panel can be visible at a time. In your application you can control what is visible on the PDA at any given point in time.
From the manual:
PDA VIs display only one front panel at a time. Calling a subVI that shows its front panel when called causes the subVI front panel to obscure the front panel of the calling VI.
