As the warm air rises and moves toward the poles,cooler air moves from the poles toward the equator to replace it. Resource:Factors of Weather:Air movement Close to the Earth (science sheet)
Basically, the sun heats the earth and its atmosphere causing differences in air temperature. The warm air rises from the equator and travels towards the poles.
When an air mass forms near the poles it has warm air. This will be a large body of air which will have homogeneous moisture.
It pushes the warm air above the cold air
Toward The Poles
Yes
Away from the poles because the air near Earths surface is warm.

In a global convection cell, warm air rises at the equator due to the intense heating from the sun. This rising air then moves towards the poles, gradually cooling and sinking as it does so. The cooled air then flows back towards the equator along the surface to complete the convection loop. This process is responsible for creating and maintaining the global wind patterns and weather systems.
It forms a warm front. Along with this nimbostratus, altostratus, cirrostratus and cirrus clouds are formed.
The difference in air pressure causes wind, air motion, because the greater the pressure difference the faster wind moves. Warm air is less dense, it moves toward or up to the poles. at the poles it will sink and the cold air will go to the equator creating the moment of of air.
