  Energy and mass are not the same thing. For one example, a photon
  has energy, but not mass. (I already gave this example before.)

  The capital "E" is mass, the small "e" is an electron.

>Do photons attract one another? Do they bounce off one another?

  There is photon-photon scattering in QED (virtual charged particle
  loops), but it is a very weak effect that rarely matters in practice.

  In general relativity, photons should attract each other, but
  this effect should be very weak and should hardly be observable.

  Both effects are so small they have never been measured directly.

  Photons are usually not that localized like tiny balls that
  have a sharp distance. They are being described by quantum
  electrodynamics, which does not take gravity into account. 
  On the other hand, general relativity does not take quantum effects
  into account. We do not yet have a theory of everything.
