No. it will not. The fan does not cool the room. It only circulates and recirculates the air in the room. We get cooled by the fan because it evaporates the sweat from the body, and also because the heat from the body is transferred to the circulating air.
In fact the running of the fan will heat up the room, since the continuous rotation of the coil results in the coil and the adjoining body getting heated and radiating the heat to the surrounding air.
Note: The only way to cool a room using a fan is by keeping small pools or keeping large containers with water in the room. Evaporation of the water in heat causes cooling.

Fans do not cool the air. They just move the air around. As a matter of fact you are adding energy so it will heat the room, not cool it.

No. In fact, the heat of the electrical motor in operation will slightly increase ambient temperature. However, a person in the room may feel cooler if the fan is directed onto the skin surface, which aids evaporation of perspiration and decreases skin temperature.

The fan will actually add energy to the room by doing work on the air molecules, not to mention the heat from the motor, and thus tend to raise the ambient temperature.

If it's a ceiling fan, then no. The ceiling fan acts to create a breeze, which makes it feel like it's cooler than it is. It doesn't actually cool the room down.
A window fan will, though. It can suck in cooler air from outside, or suck out warmer air from inside. I don't think that it will make enough of a difference to warrant leaving it on while you aren't there (all that wasted electricity).
Hope this helps!

No. A fan does not cool things, it just moves air around. The reason a fan feels cool, is because your body heats up the air around you. The fan moves that air to a different place, and blows unheated air to you.
An air conditioner is different, as that blows cold air.

depends on the thermal conductivity of the room and ambient temperature
If you have large single-glazed windows, thin walls, no insulation etc then moving the air across these surfaces will bring it closer to the outside temperature, either hotter or cooler, a bit faster than if just left to circulate around on it's own
