Wien Bridge or phase shift oscillator for sine wave. A comparator connected to an integrator for the square and triangle waveforms. For the ramp,do an online search for sawtooth waveforms, then if the ramp is required to be above the zero axis then offset the output from the sawtooth by using a summing amplifier, with one input as the positive dc voltage of what it takes to shift the waveform and the other input will be that of the sawtooth wave.

Good luck :D
