If nitrogen is colder, please tell me what else is colder than liquid nitrogen.

Nitrogen condenses at 77.36 K and solidifies at 63.15 K (at standard pressure). Apart from helium (which condenses around 4 K) there is liquid hydrogen, liquid argon, (by logical extension also liquid neon) and even liquid oxygen which condenses at lower temperatures.
It might be possible to keep nitrogen in a liquid state below 63.15 K at higher pressure, so you cannot rule out that non-boiling liquid nitrogen is colder than 77.36 K.

Liquid helium is colder, about -268 degrees Celcius, while Nitrogen is only -196 degrees Celcius. In general, anything with a smaller atomic radius will have be a cooler liquid (like liquid hydrogen, for example). Anything larger will have hotter liquids (like metals).

Helium. In order to get the crystals to form you have to add pressure.
