When the threshold energy is met, will electrons be emitted? Or does the energy of the photon have to exceed the threshold energy in order for electrons to be emitted?

The threshold energy is the bare minimum energy required for an electron to be broken off.

I think that the threshold energy has to always be greater than or equal to the rest energy in order for the electrons to be emitted.

Energy below a certain threshold frequency, no matter how intense, will not cause any electrons to be emitted. Energy above the threshold frequency, even if it's not very intense, will always cause electrons to be emitted.

If threshold energy is surpassed, electrons will be emitted. Given the amount of energy is greater than threshold, the number of electrons emitted is dependent on intensity.
