All ports can be used simultaneously -- please note the USB C limitations below.

The far left port is USB C Power input. It will not accept data input or data output.

The middle port is HDMI which outputs video and audio with the following specs:
1080p at 60Hz
UHD (3840 by 2160) at 30Hz -- Commjonly referred to as 4K.

The far right port is USB 3.0 A data in and out.

Yes, it's possible to use a hub.

It only provides 55W of power. It's enough to keep the 2016 15" MBP charged under normal usage, but under heavy load, the battery will drain even while plugged in. I discovered this today while video editing.

The iPad Pro has a single Lightning connector - it's not possible to plug a USB-C adapter into a Lightning connector.

You can set the HDMI monitor to "Mirror" or to "Use As Separate Display" (to extend your desktop) in the Displays/AirPlay menu.

That will only work at 1280 x 800 60 Hz (Single Link, not Dual Link).

Many (or all) HDMI to Dual Link DVI-D adapters do not actually support Dual Link signals. The female Dual Link DVI-D connector of those adapters has a receptacle that accepts a Dual Link male cable (more pins than Single Link cable), but only the Single Link signal is passed (because HDMI is Single Link). They don't do any conversion at all.

You need a USB-C to mini DisplayPort female adapter. Then you can connect an Apple Mini DisplayPort to Dual-Link DVI Adapter. You can tell it's a real Dual-Link adapter because it requires extra power which it gets using a USB connection.

You could also use the mini DisplayPort output of a Thunderbolt 3 dock such as the OWC Thunderbolt 3 Dock.

Or you could use the mini DisplayPort output of a USB-C dock. Some support 4K 30 Hz and USB 3.0. Others may support 4K 60 Hz but only USB 2.0 (because USB-C is slower than Thunderbolt 3 so it can't support both 4K 60 Hz and USB 3.0). Either will work with 2560 x 1600 60 Hz.

The Thunderbolt 3 ports of the iMac and MacBook Pro support both USB-C docks and devices and Thunderbolt 3 docks and devices.

I got my answer by going into an Apple store and testing. The answer is no. The USB-C port on these adapters are strictly for power input. They can't carry data in either direction.

Also, the original reason that I asked the question was specifically to find out if it would be possible to add another USB 3.0 port (with type A connector) while a SuperDrive was plugged into the USB port on this adapter. The SuperDrive will not work in any other configuration with the new 12" Retina MacBook (that is, it won't work with any hub). So the answer, again, is no: if you want to use a SuperDrive with a new MacBook, it will consume the only USB port, and no other USB devices can be used at the same time.

If it's a MacBook or 13" MacBook Pro, yes the USB-C Digital AV Multiport Adapter can charge it. However the 15" MacBook Pro needs a full 85W to be able to operate fully *and* charge the battery, so if you have that model you will NOT be guaranteed a battery charge through this adapter. After being very frustrated by my laptop not charging I finally found support doc HT207256: "MacBook Pro can receive a maximum of 60W of power through the Apple USB-C VGA Multiport Adapter or USB-C Digital AV Multiport Adapter. For the best charging performance on MacBook Pro (15-inch, 2016), connect the power supply directly to your Mac."
