Same pitch but with different loudness
Wavelength (represented by the Greek letter lambda) is inversely proportional to frequency. Two waves may have different amplitudes but identical wavelengths if they have identical frequencies. Further, a sine wave and a square or sawtooth wave may have the same wavelength even though they do not look similar and have different amplitudes, as long as their frequencies are identical.
Yes, they can.
No. In order to be coherent, the light waves have to be in phase and stay in phase, and the only way for that to happen is for them to have the same wavelength and frequency.

No, they're all waves, they're all the same!

It depends on the frequency of the waves. Are we assuming here that one wave is acting as destructive interference to another wave?. If they have the same frequency, then the amplitudes should combine to produce a wave with a smaller amplitude than the original (two?) waves. Otherwise your results will vary.
Wavelength x frequency = velocity, so if the frequency is the same for two waves moving at different velocities, the faster wave must have a longer wavelength.
Imagine this... Take a smooth pond of water. Take a small pebble and toss it into the pond. Take notice of the ripples created, both the frequency and amplitude. Now take a larger rock and toss it into the smooth pond. Take notice of the ripples it creates. The same frequency with a larger amplitude. The stronger source created larger amplitude waves. This is how two waves can have the same frequency but different amplitudes - a stronger source power.
Only if their speeds are different.(Wavelength) multiplied by (frequency) = speed of the waveIf the speeds are the same, then different wavelength means different frequency.
This question isn't finished...hard to answer, but if two waves with the same amplitude and wavelength travel together, and their phases are lined up exactly, they will combine to form one stronger wave with twice the amplitude, but still the same wavelength. If the phases are off by 180 degrees (hopefully you know what that means, if not, then think of a sine or cosine curve, if that helps, anyway:), then the waves will cancel each other out and cease to exist.
The wavelength would decrease - in inverse proportion.
