Yes, as you increase the force exerted by pushing the crate, friction between the crate and the surface will also increase. This is because friction is directly proportional to the normal force between the surfaces and the coefficient of friction. More force results in a greater normal force, leading to increased friction.
The friction force exerted on the crate by the floor is equal in magnitude but opposite in direction to the pushing force you apply to the crate. If the crate is not moving, the friction force is static friction, and it adjusts its magnitude to exactly match the applied force to keep the crate at rest.
You need to push as much as the force of friction is.
For every action there is an equal and opposite reaction, so if you push on a crate, the crate pushes back with a normal force equal to the force exerted. Thus, expect a force of 50 N to push back at you. However, if you meant the normal force of the ground exerted on the box, then that would included the 50 N force and the weight of the crate.
There's less friction over a smooth concrete sidewalk
You would increase friction so that you wouldn't slip, by using the brakes on your car of bike you increase friction to stop yourself. Hikers increase friction between their feet and the ground by wearing hiking shoes that grip the ground better. Tires on cars that create more friction make the car go faster, because instead of sliding, the tires grip the ground and push off.
The direction of friction on the crate is opposite to the direction in which it is sliding. In this case, since you are pushing the crate to the right, the friction will act to the left in order to oppose the motion.

If the crate doesn't move, then the forces on it are balanced, and they add up to zero.The force of friction is equal to the force of your push, and acts in the opposite direction.Neither you nor the friction does any work.Note that as long as this is going on, these statements are all true regardless of whetherthe floor is level or sloped.

I do not believe it would be easier to push do to the fact the crate would then be top heavy and would have the tendency to tip over easily. Unless the center of gravity was towards the bottom and Johnny was pushing at the bottom.

friction pushes east
A higher coefficient of static friction increases the static frictional force. A greater normal force also does this.
Increase the normal force, or push down on it more (add more weight). friction = μ normal force μ is the coefficient of friction which is different for different surfaces
