Light on the right means the moon is waxing (going towards a full moon), while light on the left means the moon is waning (going from a full moon).
When the right half of the moon is illuminated it would be called first quarter. (That's when you see the Moon from the northern hemisphere.)
Waxing moving towards a full moon.
Half of the Moon, just like Earth and the other planets, is more or less illuminated all the time. The half that is illuminated is the half that faces the Sun. The illuminated half continually changes as the Moon orbits and revolves. The exception is when the Earth gets between the Moon and the Sun, shading the Moon. (an eclipse).
If you live in the Northern Hemisphere, the left side of the moon is illuminated. If you live in the Southern Hemisphere, the right side of the moon is illuminated. Regardless of hemisphere, the western half of the moon is illuminated during the waning moon phases.
Half (50 percent) of the moon is illuminated by the sun at all times, just as half of earth is always illuminated.The thing that changes is: How much of the moon's illuminated half can we see from earth ?

No. Only half of the moon is illuminated at any one time. During a full moon, the half facing Earth is fully illuminated.

The moon. Half moon. OneHalfMoon.

A "gibbous" Moon has between 51% and 99% of the illuminated side of the Moon visible from Earth. Just to be precise; the Moon is always 50% illuminated. The Moon is a rocky ball, half in sunlight and half in darkness. As the Moon orbits the Earth, the same face of the Moon is always visible. From the Earth, we see "phases" of the Moon as the Moon orbits the Earth. At the new moon phase, the illuminated half of the Moon is the "far side" of the Moon; at the full, the illuminated half is the "near side".
Light on the right is waxing - getting larger. Light on the left is waning - getting smaller.
Like the Earth, the Moon is a sphere which is always half illuminated by the Sun, but as the Moon orbits the Earth we get to see more or less of the illuminated half.
