Does photon have upper limit energy(beyond gamma-ray) ???Thank you !!

mmm....not really sure..... but perhaps the Planck scale is the ultimate (so far)... you may have problems if your photon wavelength is shorter than the Planck length or at least the rules of the game may change (?)

yes- planck energy- a photon at planck energy would have a wavelength equal to the planck length-

No. There is no upper limit.
The Planck energy is large, but is not a limit.

You may consider that a frequency higher than an inverse planck time is not meaningful in current theories, so that we cannot give a clear meaning to a photon energy higher than 1/sqrt (hbar * G / c^5) * h.
