As far as we know.
Pulsar, since you would need some mechanical device to produce radio waves.
I had to think for this one but me being eleven I'm surprised nobody could answer but there are none on earth that i know of its in space a star, a star gives off radio waves.
uv rays can give u sunburns but radio waves cant

Radio waves are harmful to people because they give off radiation. Radiation is known to cause cancer in humans.
Yes.
Warm objects emit infrared waves, which are a type of electromagnetic radiation. These waves are not visible to the human eye but can be felt as heat.
Quasar actually means quasi-stellar radio sources so we thought that it was giving off radio waves but we did not put into account the redshift that causes the stretching of the wavelength meaning that it most likely gives off microwaves.

mobile phones give off radio waves to special stations which are built especially to connect calls, as they used to have an operator this is what now is used instead of the operator at this modernised age.
Yes, black holes can emit radio waves. These radio waves can come from material accelerating near the black hole before being consumed, or from the interaction of the black hole with its surrounding environment. Studying these radio emissions can provide valuable information about the properties and behavior of black holes.
All stars and stellar remnants.
