: If the graviton is massless (at rest) and travels at light speed.......then does it too have energy just like the photon?

It is massless yws it is the momentum/energy carrier for the gravitational field.

:Is it then subject to the same behavior as a photon in a gravitational field? This would mean that gravitational lensing of gravitons would make us get pulled toward something that is actualy in another place in the night sky, am I correct. It's kinda like getting pulled in the wrong direction, because of lensing. Is this possible or does it even make sence?

To an extent yes. For instance charge is the source of electromagnetic fields. It is because the photon carries no charge that electromagnetic waves obey linear differential equations. Energy and momentum are sources for gravitation. Gravitational waves are nonlinear outside of the limiting case of a linear approximation due to the energy and momentum carried in them by the graviton. If the photon carried charge electromagnetic waves would not be linear as they are.
