It seems like 5 pin connector

I have nexus 5 and by looking at the USB port it seems like it has only 5 pins and probably there are no pins on the other side of the plastic. Can not tell with 100% confidence unless I open apart my whole phone. But my friend has Galaxy S4 and looking at the top side of the Galaxy S4 I there is a small dent on the top side of the port whereas there is no such dent in Nexus 5 port so it seems that Galaxy S4 port in non standard but Nexus 5 is standard probably only have 5 pins. If this is correctly sadly we can not enjoy features like Samsung Smart Dock on Nexus 5. At the moment I am trying to achieve using Game Pad and Charging the Phone concurrently on Nexus 5 but probably it is not possible may be possible with some special Kernel, there is one such kernel for Nexus 7.
