Adding a DC source to a square wave signal will alter the base line of the wave without changing the peak-to-peak value. For example, if a square wave has a +4V baseline and a +2VDC source is introduced, the resulting square wave will have a +6V baseline. This of course will also affect the high and low peaks of the signal. Assuming that our example has a high peak of +9V and a low peak of -1V (with a total of 10V peak-to-peak), the added +2VDC source would result in a high peak of +11V and a low peak of +1V; however, the total peak-to-peak value remains unchanged at 10V peak-to-peak.
Your question doesn't give enough detail. AM typically stands for amplitude modulation. It is how AM radio works. A constant frequency is transmitted and the amplitude is varied to modulate the carrier wave with an information signal such as a song. Hence if you were examining how an AM signal changed you would see changes in the peak-to-peak voltage of the carrier frequency waveform.
No, the peak-to-peak voltage is 2sqrt(2) times as much as the rms for a pure sine-wave.
This depends on the duty of the square wave - if it is 50%, then it will be 1/2 the peak. If it is 33.3%, then it will be 1/3 the peak.

maximum and or minimum peak of any signal measured on an oscilloscope
An Oscilliscope is used for measuring signal voltages and the wave shape in an electrical signal. One can find detailed information about them on Wikipedia.
In science, the height of a peak or a trough is the maximum distance from the peak to the baseline or from the trough to the baseline. It represents the amplitude of the wave or signal at that point.
A 120V AC signal (such as at a power socket) is a sine-wave with a peak amplitude of about 170V and -170V or 340V peak-to-peak. A half-wave rectifier is basically a single diode which will clip off one half of the cycle leaving the other with a slight reduction in voltage. A silicon diode has a forward voltage drop of about .7 (seven tenths) of a volt, so if the input signal is 170V peak (340V Peak-to-peak), the output would be about 169.3V peak.
You can obtain a square wave from using two zener diodes which have a threshold significantly under the sinusoidal signal. For example: An input sinusoidal signal at 50V with two 10V zener diodes, the first in foward bias and the second in reverse bias. The output voltage will have a square wave form with 20V peak to peak.
the maximum value of the dependent variable of a wave/signal/response is called the amplitude of that wave/signal/response respectively .
A sine wave centered at zero will have a positive peak that is the same magnitude as the negative peak. This can be offset so the negative peak magnitude does not match the positive peak magnitude. For example a 1volt peak - neutral sine wave could be DC offset by 1 volt so the positive peak is at 2 volts and the negative peak is at 0.

Vpp is Peak-to-Peak voltage, in other words, in AC voltage, the peak-to-peak voltage is the potential difference between the lowest trough in the AC signal to the highest. Assuming the reference to the voltage is zero, Vpp would be twice the peak voltage (between zero and either the highest or lowest point in the AC waveform). Vrms is the Root Mean Square voltage, think of it as sort of an average (it's not quite that simple). For a sine wave, the RMS voltage can be calculated by y=a*sin(2ft) where f is the frequency of the signal, t is time, and a is the amplitude or peak value.
In a wave, the distance from peak to peak is called the wavelength. It is the physical distance between two similar points in the wave's cycle, such as two consecutive peaks or troughs.
