What type of cable do i need to charge my Acer laptop using one of the usb charging ports? The laptop has a barrel-type 19v charging port.

The charging ports on the dock are for charging devices designed to charge via USB (e.g. mobile phones, tablets, etc.) I don't don't believe the ports can supply the necessary voltage and amps required to charge your laptop, even if a compatible cable was available. The device is not a dock in the purest sense; you should think of this product as a USB 3.0 hub with integrated audio, video, and network adapters permanently connected to it.

Is it possible to run 2 monitors with the laptop closed?

It's definitely possible, however it is up to your computer setting. If you are on a mac you should google about "clamshell (display closed) mode". https://support.apple.com/en-us/HT201834on windows you can change the behavior in Power Management to "do nothing" when you close the lid.https://www.youtube.com/watch?v=ODxQchBckPU

How can a single usb port support two monitors, gigabit ethernet and various other peripherals? explain the magic to me please.

USB 3.1 Type C is an Apple concept that is now a standard and supports multiple signals to be sourced through this special port. Video, audio, USB, Ethernet and power can all be transmitted through this new type of connection.

Does this work with windows 10? what software does the ds-rica use to manage the video?

It does with Windows 10. You need to make sure to download the latest Display Link drivers.
