I am going to connect a fan to the parallella board. It seems that there is a J15 (pin hole) as described in
https://www.parallella.org/power-the-parallella/ (mounting holes section) which I have to connect the +5V of the fan to that.
However, the GND pin (or holes) is not clear for me. Where it is?

The Parallella board has four mounting holes. One is connected to +5 V, all others are connected to GND.

You mean that the two holes near the barrel pin (the external power supply pin) are +5V and 0V?
Or both are connected to+5V?

I wrote that one mounting hole is connected to +5 V and that all others (that means: three mounting holes) are connected to GND.
If you don't trust me, then just measure the voltages yourself.
