1 engine, 3 temp sensors?

It looks like my car has 3 coolant temp sensors. I need to know what each of them do, so that I can check and replace them if they are bad. Below is a picture of my car's 2.3 8v engine's front side(1st pic - thermostat housing, 2nd pic - engine fan)
I have numbered parts that look like sensor. The sensor #1 is more complex. It has 4 wires coming to it. The others just have 1 wire.
