The maximum flow rate through a 1.5 inch pipe is typically around 9 gallons per minute.

To find the maximum flow you would need to know the maximum pressure. A typical fire nozzle pressure would be up to 100 psi with a diameter of 1 to 1.25 inches. The GPM would be between 300 GPM and 460 GPM through the nozzle. If it were simply a 3-inch pipe with an oversized pump, running at 100 psi with no nozzle, you could (in theory) move over 3,000 GPM through the pipe (ignoring friction loss). Even at 80 psi, a master stream through a 2-inch nozzle moves over 1,000 GPM.
Maximum PSI rating is on the outside rating of the pipe
If the flow velocity remains the same the flow volume will increase by the square of the diameter ratio.(2/1.25) = 1.6 = diameter ratio1.62 = 2.56 more flow volume through 2 inch pipe compared to 1.25 inch pipe.
Yes, easily.

The maximum flow rate for a 1 inch diameter pipe is typically around 8-12 gallons per minute. To calculate the maximum volume, you would need to multiply the flow rate by the amount of time the water is flowing.

that's what she said
question cannot be answered because it depends on the water pressure
