No, it's losing potential energy, since it gets lower.
No, it is not.
When a plane is landing on the runway, it primarily has kinetic energy. As the aircraft descends, its potential energy decreases but is converted into kinetic energy as it gains speed. The kinetic energy is then used for braking and stopping the plane on the runway.
A person parachuting from a plane has already acquired potential energy by rising to whatever altitude the plane is at-this energy has been obtained from the fuel used by the plane. This energy is then turned into kinetic energy as a result of the earth's gravitational attraction, and the parachutist goes into freefall. Braking the speed of fall to make a safe landing, the kinetic energy is returned to the air which is slowing the parachute. The net change when the person lands is zero.

A person running is not an example of potential energy. it is an example of kinetic energy.

A plane in the air posseses gravitational potential energy or stored energy. If the pilot shuts the engine off the plane releases that energy.

The plane's landing gear is deployed as the plane is descending and nearing the runway.

the plane landing like a roket crashin gon the heat
The potential energy of any body of mass M kg raised by H meters above the earth's surface is M x H x G (G = 9.81 meters/sec/sec). It doesn't matter whether it moves up a plane or vertically, it is only the vertical rise that determines the potential energy. Of course on a plane the movement may create friction which means you have to put extra energy in, but this extra energy does not count towards the potential, it is probably lost in creating heat.
No.
Elevational potential energy is converted to kinetic energy and heat in the air as air friction sets a terminal velocity. If a parachute is not used, some additional energy is lost with the associated screaming...
Kinetic energy increases; potential energy decreases, because the object is now in motion
