Over 1000 degrees centigrade
Yes, there was a significant lava flow during the eruption of Mount St. Helens in 1980. The eruption caused the collapse of the volcano's summit, leading to a massive explosion and the release of a pyroclastic flow. This flow melted the ice and snow on the volcano, mixing with ash and rock fragments to create a fast-moving lava flow known as a lahar.
No. Recent eruptions of Mount Merapi have produced pyroclastic flows instead of lava flows. Pyrolastic flows are fast-moving currents of hot ash, rock, and gas. There is no way of stopping or deflecting them.
It is a lava flow, and has an AA (ah-ah) lava flow
A mafic lava flow will move faster than a felsic lava flow due to its lower viscosity. However, felsic magma tends to erupt explosively, producing fast-moving pyroclastic flows instead of lava flows.

Mount Hood has a few steam events, but has not had a lava flow in almost two centuries.

it has pyroclastic flow and has small eruptions of ash.
Lava can't flow violently. Highly explosive eruptions such as the 1980 eruption of Mount St. Helens do not produce lava flows: they produce clouds of ash, gas, and pumice. Mount St. Helens has produced "quiet" lava flows at times.

Mount lava flow or parchment desert
Dacite lava flows at speeds orders of magnitude slower than mafic lava.
