Only 16 of the ports are UP (Unified Connectivity) ports.  So up to 16 possible  FCoE ports.
Unified ports 16 ports (Ethernet; FCoE; 2/4/8-gigabit FC)

All 72 of the ports can be 10g Ethernet.

16 of the ports are "unified ports".  Another way to think of the UP ports is that they are dual personality.  They can be Ethernet or they can be FCoE.

Yes. Any of the ports can be used for 10g connections.  The media type (fiber, twinax, UTP) is dependent on the SFP+ that you install.

Hi,

You can use N5K for both of port types as you want. But you need to configure and after it switch reboots !.
Also there are some limitations like:
1- ethernet ports are defined from first port to the last port.
2- FC ports are defined from last to first port.

you cannot use like 1,2,3,4 ports as ethernet, 5,6 as FC , and 7,8 ports as ethernet again.
you are deviding switch by ASIC's. 2 parts, first part ethernet second as FC. full ethernet or full FC is possible.

2 commands to see what you can do with that port is:
show interface e1/1 capability -> shows what N5K supports as a port.
show interface e1/1 transceiver -> shows what your transceiver supports plugged to that port.

Br,
