The magma is primarily granitic/rhyolitic, but there are occasional basaltic lava flows.

Yellowstone National Park.
The magma in the earth had to go somewhere and it has accumulated around the Yellowstone area for many thousands of years.
No. On the contrary, seismic studies indicate that the magma chamber under Yellowstone is cooling. Much of the magma has solidified, probably too much for a significant eruption to occur.
It is an acidic magma and has a huge caldera.
Yellowstone is not on a plate boundary, but is a 'hotspot' where magma seeps from the mantle to the surface, or near the surface. The case is the same for Hawaii.
Lava comes out of volcanoes and turns to magma and ash that goes in the air, and magma that slowly flows on the ground.
From the collapse of a massive magma chamber after it last erupted.
