Yes. Emission and temperature are not linked as far as I am aware (at normal temperature ranges anyway)

Yes, but it will emit less thermal radiation than a hot object. All the other hundreds of kinds of radiation will be emitted as normal. For example an x-ray machine will work even if it is cold.

Any object having temperature greater than 0 K continuously radiates heat. It is because every system in the universe tend to have least amount of energy with it, i.e. to become more stable.
Practically 0 K is unattainable. So every object in the universe continuously radiates heat.
It is different that they radiates at a lesser rate than they absorb from their surrounding hotter bodies.
Rate of emission is directly proportional to the fourth power of the absolute temperature of any body(stefan's law)

Yes they can, radiation comes from the nucleus of an atom which can and will emit radiation NO MATTER what state it is in. Hot, Cold, reacted, split, etc.

Yes they emit radiation but they absorb more than they emit if in proximity to a hot body.

The COLD objects emits the condensed vapours!!

any object above absolute zero (-273.15°C) is an emitter.
