On the electromagnetic spectrum, radio waves have the longest wavelength (so the lowest frequency and lowest energy).

Amount of photons corresponds to the amount of energy a wave carries. Lets say white light(contains all colors in vis spectrum); you have two lights and one seems brighter. These both have the same wavelength and frequency because they are both white lights. But one is brighter because it has more photons, carrying more energy. This corresponds to the amplitude of the wave. So the brighter light would have a larger amplitude.

If a radio wave has more photos, it means its wave has a larger amplitude but still the same frequency and wavelength.

Refraction does separate different wavelengths(thus different frequencies), because waves of different wavelengths passing through another medium with a different refractive index, travel at a different speeds that causes the observed changes in direction and separation of the waves.
