Depends on the other surface. Coefficients of friction are generally tabulated for pairs of materials. Emery cloth on Teflon, for example, will have a lower coefficient of friction than emery cloth on rubber.
With what material? Coefficient of friction is for two materials.

The larger the value of μ (aka Mu, the coefficient of friction, the greater the frictional force on an object. For instance, steel on nonlubricated steel has a μ of 0.58 while steel on lubricated steel has a μ of 0.06.

No, coefficient of friction is dependent on the materials in contact, not their mass. However the FORCE of friction will increase as the mass increases in this case.
The larger the value of μ (aka Mu, the coefficient of friction, the greater the frictional force on an object. For instance, steel on nonlubricated steel has a μ of 0.58 while steel on lubricated steel has a μ of 0.06.
The coefficient of friction is a scalar value with no dimension. It is simply a ratio of the force of friction between two objects, to the force pressing those objects together (often the normal force). Slippery surfaces have lower coefficient of friction than rough surfaces.
Air and friction both being fluids, the resistive forces between them are more related to drag than friction.
There is no minimum value for the coefficient of friction. And the linear acceleration will depend on its unknown value.
