How do you make a circuit so that one switch will turn on/off all the lights (3 lights) and a second switch will change the lights from all being the same brightness to all being different brightnesses?

Parallel circuit. On a wire you put the lights and one switch, on the other you put a resistor and another switch. (and the third wire contains the generator)

The three bulbs can be connected in series to the battery B1, such that when switch SW1 is turned ON all three bulb turns ON with the same brightness. We now have the three resistors R1, R2, and R3 connected in parallel to the lamps LMP1, LMP2, and LMP3 respectively when SW2 turn on. SW2 is a Three Pole Single Throw switch. Please see attachment for the electric circuit diagram. ;

To build a circuit with one switch controlling all lights and another adjusting their brightness, connect three bulbs in series with a SPST switch. A TPST switch can be placed to create parallel branches with different resistors, allowing for varied brightness levels when activated. Using these basic components allows for effective control and understanding of series and parallel circuits.
