No, it CAN'T be greater, and it is usually smaller.

false; usually it takes more force to overcome static friction which is higher
false. Kinetic friction is the friction acting upon a moving object. It would be the frictional force against you if you pulled a box across a table. Static friction is the frictional force needed to overcome to get an object at rest into motion.
Static
By my understanding, this is due to the fact that it is easier to keep a moving object in motion than it is to accelerate it from a resting position. When a force is exerted on a stationary object, acceleration relies on that force alone. However, with a moving body, the momentum of the object reduces the force needed to overcome friction.
While the box is moving in a straight line at a constant speed, the push only has to overcome the kinetic friction. Whatever the speed is, and whatever the weight of the box is, 4 pounds of push IN THE DIRECTION THE BOX IS MOVING will keep this one going.
As a rule, sliding friction is greater to overcome than fluid friction. However, the variables could be manipulated to show it in both lights. The mass, weight, surface area, types of surfaces, speed, ect... are all variables in which the amount of force is needed to overcome sliding friction. While density and viscosity are major variables in fluid friction.
A car accelerates when the engine produces more power than what is needed to overcome friction. The car reaches its maximum speed (on the level) when all the engine power is being used to overcome friction.
