These have to do with the hydraulic density. In automobile, the density increases therefore making the hydraulic ratio to displace more than any hydraulic ratio in a displacement.
By "Hydrostatic" systems one tends to mean "closed loop hydraulic systems". That is hydraulic systems comprising a pump and motor hwere the pump supplies the motor whose return side supplies the pump. The speed and direction of rotation of the hydraulic motor being changed according to the displacement angle of the variable displacement axial pison pump. "Open loop hydraulic systems" on the other hand comprises various motors often one or more "linear motors" (hydraulic cylinders). When using hydraulic cylinders in hydraulic systems one needs a reservoir to be able to hold the various volume need of the cylinder. (the displacement on the piston side is usually bigger than the rodside). The reservoir needs a "breather" due to the varous displacement needs hence the "open system".
Instead of hydraulic pumps, hydraulic gear motor does not work. Hydraulic pump hydraulic motor blade is used instead.

Internally, they're pretty much the same. The difference is the operation expected of it - a hydraulic pump converts mechanical energy to fluid energy, whereas a hydraulic motor converts hydraulic energy to mechanical energy.

yes.only positive displacement pumps can be used in hydraulics
Displacement is the measure of how much fluid it takes to turn the hydraulic motor shaft per revolution. It is typically expressed in cubic inches or cubic centimeters per revolution. Given the same flow rate and pressure, a larger displacement motor will turn slower than a smaller displacement motor. A larger displacement motor will also produce higher torque than a smaller motor. So as displacement increases, torque goes up and speed goes down. This makes sense as torque multiplied by speed equals horse power. For a same input horsepower (pressure times flow), if one value did not vary as the inverse of the other, the conservation of power would not be met.

It means how much oil is needed to make the motor turn one full revolution. If you have a 32 Cubic Inch Hydraulic Motor, you would need to push 32 cubic inches of oil through that motor to turn it once. Using the same hydraulic pump, a smaller cubic inch motor would cause higher speed, but less torque.
Instead of hydraulic pumps, hydraulic gear motor does not work. Hydraulic pump hydraulic motor blade is used instead.

Only the sweep is linear cylinder. Motor rotates the hydraulic oil pressure.
It is a hydraulic motor housing containing a vane that turns the shaft when hydraulic fluid is pump through the motor.
It is both, an electric motor runs a hydraulic pump.
