That depends on how large the puddle is - how wide and how deep and how much water is in the puddle.

The water has to evaporate.
That depends a lot on the circumstances: mainly the shape of the water's container (the key part here is, how much surface is exposed), and the temperature. If you spill one liter of water on the floor, it might well evaporate within minutes in some cases. If you spill it on a hot metal plate, it might take seconds to evaporate.
Two things, depth and surface area. A puddle is generally shallow and large, meaning there is more area for the sun to heat, which more water can evaporate at a faster rate. A glass of water is small and deep, so the process is slower. Now if you took the same volume of water that was in the glass and poured it onto the floor, the water would evaporate faster.
usually it depends if it is in a warm humid area or a normal degree temperature room.
This is not true.

it depends but i will take longer than fresh water
Epsom salt will never evaporate. If the Epsom salts are dissolved in water, the water will evaporate, leaving the dry salts covering the inside of the container.
On a boiling hot day it would take about 10-15 minutes but on quite breezy days it would take 1-1 and a half hours I think.
