Actually, the static friction is neverzero.
No, static friction cannot be negative. Static friction always acts in the direction opposite to the applied force and prevents an object from moving when a force is applied. If the external force is removed, static friction drops to zero.
The work done by static friction is always dependent on the displacement of the object it acts on.
Yes, it is generally true that kinetic friction is always greater than the maximum value of static friction.
In the reference frame of the interface between two surfaces, static friction does Zero work, because there is never displacement between the surfaces. But it can be positive , negetive or zero with respect to choosen frame of reference.
Kinetic friction is the friction that applies when an object is moving; static friction is the friction that applies when the object is not moving. Static friction must always be greater than, or equal to, kinetic friction.

The relationship between static friction and the coefficient of static friction (s) is that static friction is directly proportional to the coefficient of static friction. This means that the force of static friction acting on an object is determined by the coefficient of static friction between the object and the surface it is in contact with.
Yes, look at "what is static friction?" Static friction is also known as starting friction.
Sliding friction is always less than the static friction by small amount.
That is called static friction.
static friction is higher in most cases, if you're talking about the coefficient of static or kinetic friction
