Connect two monitors using DVI and/or VGA to USB-C
It is possible to connect a VGA and a DVI display to one USB-C port on the MacBook, but you need two USB-C adapters in a daisy-chain fashion and a HDMI-DVI adapter.

First you connect the USB-C Digital AV Multiport Adapter (part number MJ1K2AM) to the MacBook USB-C port, then you connect the USB-C VGA Multiport Adapter (part number MJ1L2AM) to the USB-C port on the Digital AV adapter.

To get the DVI you also need to connect an Apple HDMI to DVI Adapter (part number MJVU2AM) to the HDMI port on the Digital AV adapter which provides you with the DVI port you need.

Now you have a DVI port and a VGA port available and only one USB-C port is used on the MacBook.

The setup (minus the HDMI-DVI adapter which I don't have) would look similar to this:
