sky diving jump

 jump from gyrocopter , para motor or paraglider can be defined as a free fall jump and be logged in skydiving logbook ? 

Yep. It doesn't matter what kind of aircraft it is. A freefall jump from any aircraft in flight is a skydive and can be logged. Whether or not the jump is legal is a separate question.

is there also any regulation on minimum jump altitude from these kind of aircrafts ? 

The rules don't change for aircraft type

https://www.uspa.org/SIM/2#1I

For jumps to count toward USPA licenses, ratings, and awards, they must comply with USPA Basic Safety Requirements -- see Ian Harrop's post. 

However, the US FAA does not have a minimum jump altitude or a minimum opening altitude.  Note that it is not possible to set a new record for minimum altitude.  The best you can do is tie the existing record.

For minimum altitudes for jumps outside the US, check with your local skydiving/aviation authority.

In the US, jumps from Part 103 ultralights (which includes most powered parachutes and paragliders, as well as some gyrocopters) is generally prohibited by the FAA, since the jumper would be a passenger, not a student pilot undergoing flight instruction.  Additionally, skydiving from Experimental and Restricted category aircraft is also generally prohibited by the FAA.
