The moon orbits the earth in just a little under 28 days. The earth is blocking sunlight from reaching the moon at certain angles which cause the phases of the moon. Everyone sees the same phases because of this.
Yes. Everyone on earth for whom the moon is visible sees the same phase at the same time.

The crescent Moon implies a gibbous Earth, as seen from the Moon.
The phase of the moon depends on it position in relation to the earth and the sun. For instance, when the moon is in between the earth and the sun, this is the new of full moon phase.
As seen from the moon, the Earth is a brighter source of light than the moon is as seen from the Earth. This also depends upon the phase of the Earth, just as the brightness of the moon varies by phase. A full moon and a full Earth are in the brightest phase.
New moon!
