There are various scenarios where the 2016 mbp can achieve multiple displays through one port but it isn't easy. For the most part In Mac OS, using a USB-C to DisplayPort/HDMI cable/adapter, you can only achieve one display (ignoring stretched multi display solutions) Here are a few ways around this:
1. Use a TB3 to Tb2 adapter, connect a Apple TB display then daisy chain a TB/mDP display off the extra TB port.
2. In Windows (only), the MacBook Pro can daisy chain to as Many displays as supported by your video card.
3. Using a thunderbolt 3 dock, you can achieve 2x DisplayPort output (1 DisplayPort, 1x usb-c)
And then there are resolution/bandwidth constraints. 2x 5k displays max (for the 2016 MBP 15), 4x 4k monitors max, etc
