do all photos have same mass

All photons have the same rest mass equals to zero. But photons are never at rest.

Every photon has some amount of energy, and according to special relativity, that energy is equivalent to some amount of mass. (That’s where $E=m{c}^2$ comes from.) A photon will be gravitationally affected as if it were made up of this equivalent amount of mass.

What determines the amount of energy in a photon is its wavelength. The energy of a photon is inversely proportional to its wavelength, so the shorter the wavelength, the more energetic the photon. Half the wavelength means twice the energy, and hence twice the mass equivalence.
$$\begin{gathered} E=\frac{hc}{\lambda } \\ h is plancks cons\tan t \\ c is speed of light \\ \lambda is the wavelength \end{gathered}$$

For example, a photon of red light (wavelength 700 nm) has an energy of about 1.8 eV (electron-volts). A photon of blue light (wavelength 450 nm) has an energy of about 2.76 eV. The wavelength of blue light is about 66% of red light, so the amount of energy in blue light is about 1.5 times as much. Therefore the mass equivalent of the blue photon will be 1.5 times as much as a red photon.
 The shorter the wavelength, the more energy, and therefore the more mass equivalence.
