The CMB originated when the universe went transparent to electromagnetic radiation, when electrons and protons first combined to form hydrogen. This is estimated to have happened some 377.000 years after the onset of the Big Bang.
The average temperature of the universe is expected to decrease over the next billion years due to the continuous expansion of the universe. This expansion will cause the overall energy density to dilute, leading to a decrease in temperature.
The lowest temperature ever observed in the universe is around 2.7 Kelvin (-270.45 degrees Celsius), known as the temperature of the cosmic microwave background radiation, which is a remnant from the Big Bang. It represents the average temperature of space.
The average temperature of the surface of Uranus is -224° Celsius.
The average temperature of the sun is around 5800 Kelvin.
Mercury has an average surface temperature (67°) closest to the Earths average surface temperature (14°C). The temperature on Mercury varies a lot though - you could argue that Mars is closer in temperature.
The universe is about 2.3 Kelvin
Yes, the sun is an average-sized star in terms of its size, temperature, and luminosity compared to other stars in the universe.

The average temperature of the universe now is 2.72548K (the cosmic blackbody radiation of the big bang cooled by expansion). There are places colder, but nothing can be as cold as 0K (absolute zero).
The big bang was the BEGINNING of the universe so there was no temperature before it :P
Yes, the sun is considered an average star in the universe.
Yes, there is a theoretical limit to temperature called the Planck temperature, which is approximately 1.416 x 1032 Kelvin. This is considered the highest possible temperature in the universe.
The average temperature is here. The average temperature is here.
The Universe was at 3000 degrees K at conception, and since then, the universe has expanded by a factor of 1000. The latest revised temperature is at 3 degrees K.

The current temperature of the universe is approximately 2.73 Kelvin, which is equivalent to about -454.76 degrees Fahrenheit or -270.42 degrees Celsius.
