The surface of Haumea is chiefly crystalline water ice. Recent models suggest that 66-80% of its surface is covered in it, with the rest being rocky.
The equatorial surface gravity on the Plutoid dwarf Haumea is estimated at 0.44 m/s2 . That's 4.49% of Earth's. If you weigh 200 pounds on Earth and somehow scored a ride to Haumea, you'd weigh just about 9 pounds there.
There is a lot of water on Haumea, though due to its cold temperatures, all of it (at least on the surface) is frozen. We do not know enough about its surface to definitively say if it has volcanoes, though other pieces of evidence suggest it might.
No. Haumea is not classified as a planet. It is a dwarf planet.
Yes, Haumea is a rocky, terrestrial planet.
A day on Haumea is very short compared to here on Earth. Haumea's rotational period is just 3.9155 hours.
According to windows2universe.org, the surface gravity of the dwarf planet Haumea is 0.44 meters/second squared. (This is compared to Earth's gravity of 9.807 m/s squared).

Of note, first, Haumea is a dwarf planet, not a planet. Although very little is known about its surface, it is highly unlikely that it has any volcanoes.

As far as we can tell, 65-80% of the surface is covered in crystalline water ice. The rest is likely rocky.
Haumea is sometimes known by its minor-planet designation, 136108 Haumea.
Haumea's rotational period is 3.9155 hours.
