Do photons have temperatures? I do not believe so, since they CAUSE temperature and ARE temperature but can anyone clarify this? If indeed they do not possess temperature then do they have energy states/levels?

You cannot assign a temperature to a single photon, which is similar to not being able to assign temperature to one single atom of matter. Temperature is just merely statistics. Photons do not individually have a temperature, but in large groups it can have a "characteristic" temperature. 

Photons also do not have kinetic energy in normal sense because they have no mass. 

So I suppose in general, you can say they do not have temperatures.
