Depending on the cycle, it is a waxing or waning gibbous moon if it is more than half visible. If it's completely visible, it's a full moon.

The object that blocks the moon when there is a half moon is the moon itself. The moon is a sphere, so only one half of it can be sunlit at any moment. The other half is dark just because the sun is below the horizon for that half of the moon. And when we see a half moon, we are simply looking at the moon just as the line of sunrise/sunset cuts across the moon's diameter.

The crescent is a design that typically will resemble a half moon. Some people actually call the moon a crescent.
This is either a "First Quarter" or a "Third Quarter" Moon.

No. When you see the whole sun-lit side, you call it a "Full Moon".
This happens about once a month. We call this the "third quarter" phase of the moon.
The waxing moon phase is when the moon is transitioning from new moon to full moon, and the illuminated portion of the moon is growing larger each night. During this phase, we can see more than half of the moon's lighted side from Earth.
The "more than 50%" moon is called the gibbous moon. When it is "growing" (appearing to get larger), it is a Waxing Gibbous; when "shrinking," it's the Waning Gibbous.
