you ask too many questions, go try them out and experiment. passengers will be impressed by the flashing numbers... and you can tell them it means anything and they'll believe you. "this number is the oxygen percentage in the air we're breathing.. it's measured in neutrons." ... "and this number is the car's age in car year's opposed to human years.".
But if you insist...
1-5 is the measurements in Celcius of various temperature sensors.
6 will show the engine's actual RPM.
7 will show the car's actual speed in km/h.
8 I don't know what a Y factor is, but I went to the liberty of searching google, and apparently it tells you this.
9 is that little flap that broke on your old car. There are flaps on side of the engine compartment that bring in fresh air, or recirculate the air in the car. This tells you what position the flap is in. (helps you diagnose if it's stuck too.)
10 is the AUC sensor. This sensor controls the fresh air circulation system in the car.
11 is the battery's voltage, measured in... volts.
12 is the version of the climate control software that is currently on it.
