The freezing point of Helium is -272.2 Celsius, which is 1 K. Nothing can achieve a temperature of absolute 0 K. It will imply no energy, no motion, which in the atomic world is impossible to achieve. The average temperature of outer space is between 2 to 3 K, so you can have liquid/gaseous helium at equilibrium.

Everything except helium will freeze if cooled enough at normal pressure and even helium will become solid when compressed. Liquid helium will freeze water rapidly.

Yes, the funny thing is that helium has a lower freezing
point than hydrogen - weird.
Hydrogen > -259.2C
Helium > -272.05C

With the correct temperature and pressure, yes.
In the case of Helium, you need a pressure 2.5 mPa and a temperature of .95K(-272.2 celcius).

Absolute zero is defined as the temperature at which molecular motion stops, -273 degrees C.
Helium liquifies and then solidifies around -267 degrees C.

Helium-4 is a liquid at all temperatures until at least 2.5 MPa pressure. He-3 requires 3-3.4 MPa depending on temp - more pressure at lower temps!

Yes, if you reach its freezing point. And I think it's about -270 degrees.

Yes, eventually. But the temperature will be in Kelvin. All things are frozen at zero Kelvin.
