sliding friction
Coefficient of rolling friction will always be less than that of sliding friction. Hence more force is required to overcome sliding friction. Because the force = coefficient of friction x normal force (ie weight of the body)
False. When sliding a bag of groceries, you are overcoming sliding friction, not rolling friction. Rolling friction occurs when a round object like a wheel rolls along a surface.
I assume this relates to a wheel. When the wheel is rolling, the surface of the wheel is not moving relative to the surface of the road when they are in contact. however, the wheel deforms slightly and because of this, the normal force slightly opposing the motion of the wheel rather than simply pushing it up. This is rolling friction or more commonly known as static friction. When the wheel is sliding, the wheel is sliding over the road's surface, meaning that there is relative movement between the wheel and the road. this is known as sliding friction or kinetic friction.
Sliding
Sliding friction is the force that opposes the motion of an object sliding along a surface. Rolling friction, on the other hand, is the force that opposes the motion of an object rolling over a surface. Rolling friction is generally less than sliding friction, making it easier for objects to move when rolling rather than sliding.

Typically not. However rolling friction is somewhat of a myth. Rolling friction is actually caused by static friction. There are really only two types of friction: Static and Kinetic. That's it! Rolling friction is caused by static friction and the coefficient of friction (which determines its strength) is dependent upon the two materials of interaction.
