They really don't have a name, so they are just called thermometers.
Unless your refrigerator has a built-in thermometer, you would need to check it with a thermometer. Purchase of a refrigerator thermometer is highly recommended.
Most refrigerators have a thermometer inside that will show the temperature. If there is not one, most stores sell refrigerator thermometers.
Not usually. An actual "meat" thermometer is not designed to be used in the refrigerator, nor are they generally of the appropriate temperature range.
A RV absorption refrigerator uses a thermistor as a thermostat. The thermistor is moved up or down to regulate the refrigerator temperature.
There are several things you can use to guestimate the temperature, but nothing else will give you a decent value for it.
