About fourty-eight hours
Approximately 14 days must elapse between the first-quarter moon and the third-quarter moon. This period represents half of a full lunar cycle, which lasts about 29.5 days.
About 22; slightly under that, by a few hours.
No. There are 29.5 days between full moons.

Essentially, yes. There is one moment each month when the Moon is PRECISELY "full", but the difference between 12 hours before the full and the full moon is only about 1%. So there is a 24-36 hour window each month when the Moon is at least 98% "full".
A full moon is between quarters.
The time between each principal moon phase is roughly a week. Specifically, from New Moon to First Quarter Moon is about 7 days, from First Quarter to Full Moon is another 7 days, from Full Moon to Last Quarter Moon is approximately 7 days, and from Last Quarter back to New Moon is around 7 days as well.
Full Moon.
about 28 days. This happens roughly every month. (month -> moon)
a full moon is when the moon is completely full and completely round. a new moon is when the moon appears to have dissapeared.
The phase that occurs between the first quarter moon and the full moon is the waxing gibbous phase. During this phase, the illuminated portion of the moon continues to grow larger each night until it reaches full illumination.
The moon in the days before and after a full moon appear as a gibbous moon. A gibbous moon is anything between a full moon and a half moon.
