This depends on many factors (nature of the solid, granulation, stirring, pressure, temperature, volume of the solvent, quantity of the solute, effect of another ions etc.) and a general answer is not possible.

Solubility is the property of a solid, liquid, or gaseous chemical substance called solute to dissolve in a solid, liquid, or gaseous solvent. All substances have a different solubility and rate of solution is as stated in the paragraph above.
water
fast
Instant coffee granules dissolve faster in hot water than in cold water.
Most chemical salts dissolve faster in hot water than in cold water.
Much faster in boiling water.
It depends on the kind of the solid
It won't. Put powdered milk in cold water to dissolve.
In order to dissolve chalk in water, vinegar needs to be added. The vinegar has acid in it that eats away at the chalk to dissolve it.
Not all solids will dissolve in water at all. Those that do dissolve do so at different rates, and it's also temperature-dependent.
depends on your definition of hot
vinegar is acetic acid and if the lollipop is acidic then it will dissolve fast as like dissolve like..
If you use warm water it'll take about half hour
