What frequency means for a single photon?

Frequency is inversely proportional to the wavelength of the photon and so in another way of indicating the energy of the photon. Remember that for a given wavelength/frequency, your photon will have a specific energy given by $$E = \text{a constant} \times \text{frequency} = \frac{\text{a constant}}{\text{wavelength}}$$ All these values measure the same thing.

It is the very well-known, which is also determines the Planck constant too:

$$f=\frac{E}{h}$$

Here $h$ is the Planck-constant, around $6.6*10^{-34} \frac{J}{s}$.

If you have mass, you can convert this to energy by the well known $E=mc^2$ formula.
