I was wondering if anyone had successfully used multiple virtual instruments simultaneously

Yes! All five of the instruments can be used simultaneously. For instance you could have a board that needs power and a digital high on a couple lines while you check current with a DMM or scope a few outputs. While getting comfortable with the software interface, a quick test is often just placing a BNC cable in loopback between the FGEN and Scope.
An example of using multiple instruments with the Windows application:

The NI-VirtualBench API can also be used to program all five of the instruments. The tail end of this video shows an example of automating both the FGEN and the Scope to perform a Bode analysis:

usrfrnly,
Absolutely! VirtualBench (all models) is designed for each instrument to be able to be used simultaneously and independently. This means you can use the DC power supply to provide power to a device under test, provide some stimulus with the function generator, and measure using the mixed-signal oscilloscope and digital multimeter.
If you plan to use it interactively I would suggest simply opening the app which provides basic control for all of the instruments. If you wanted to automate it, you can run each of the instruments seperately through the APIs, plus you can still open the app to monitor everything.
Hope that answers your question, but reply if not.

Thanks, all. I couldn't figure it out from the manual so i turned to the hive mind.
