No. If it moves, it has kinetic energy.

kinetic energy and potential kinetic energy decrease because a) the air is resisting the swinging item, so the item needs more energy (that it doesn't have) to continue swinging at its starting speed; and b) gravity is pulling it towards the earth. gravity is stronger than the small amount of energy put into the swinging item.
Primarily potential energy (possibly a little bit of kinetic energy if it is swinging back and forth). If whatever it is hanging by is severed, it will fall - transitioning from potential to kinetic energy.
A swinging pendulum demonstrates primarily two types of energy - kinetic energy when the pendulum is in motion, and potential energy - based on how high it is above the mid-point of the swing. If not for friction, a pendulum would continue to swing forever, with the sum of the kinetic and potential energy remaining constant but the distribution between the two constantly changing as the pendulum moved through its swings.
No. It is an example of kinetic energy.
No. If it moves, it has kinetic energy.
1) at the top of the swing, the swinging object has all potential energy and no kinetic energy (no speed at that moment) while at the bottom there is no potential energy but a maximum in kinetic energy, so that the swinging object is fastest at the bottom.

As the pendulum stops swinging, its maximum kinetic energy (the initial energy at the beginning of the swing) decreases, and its potential energy increases. Once the pendulum stops, it will have zero kinetic energy and maximum potential energy.

If a pendulum is at its center position, then there are two possibilities: 1). It may be swinging. Then its kinetic energy is maximum and its potential energy is zero. 2). It may be stopped altogether. Then it has no energy at all.

A swinging pendulum is moving fastest at the lowest point of its arc. That is the point where all its potential energy has been converted into kinetic energy, and it is the only point in a pendulum's arc where that happens. See related link (a simulation).
a swinging pendulum has its potential and kinetic energy changing.when the swing is at xtreme position it has ma potential energy and at mean position it has max kinetic energy
A pendulum swings back and forth with a period based on its length. When it is pointing directly down, moving horizontally with maximum speed, there is no potential energy; all the energy is kinetic. When it is maximally away from this position it has stopped and so has no kinetic energy; all the energy is potential. Thus at any one time there is the same amount of energy in a swinging pendulum but depending on where it is in its arc of motion there will be different amounts of kinetic and potential energy.
