During the entire two weeks from First Quarter to Third Quarter, more of
the moon's lighted surface faces toward Earth than faces away from it.
The moon is said to be waning when less and less of the side facing Earth is lighted. :D
The lighted half of the moon is always facing the sun. The entire dark half of the moon is facing earth at the time of "New Moon".
New moon.
If the hemisphere that is 'lit' is facing away from the earth then it is a new moon
in the new moon, the lighted half of the moon is facing the sun and tha dark side faces the earth.
That would be Third Quarter.
The moon phase "waning gibbous" appears after the moon phase "full moon".It becomes the "last quarter" or "third quarter" when the lighted part is exactly 50%of the side facing the Earth.
"First Quarter", roughly 7.4 days after the New Moon.
Not exactly. The lighted side of the moon as seen from Earth is that part that is not shadowed by the Earth.
That's "First Quarter", roughly 7.5 days after New Moon.

That's the 'Full Moon'.
