Good day guys,

Engine light turned ON.

bad MAF sensor (mass air flow), I would check it and or the harness/connector or just replace it and your other issue's may go away, the maf can be the root cause of other problems.
p0101 is a bad or malfunctioning maf sensor
p00aa is a intake air temperature error (probably directly related to the maf)
p21aa is a throttle body position error or something of that nature (could also be related to bad maf)
b2aaa is a communication error with the scanner device used to pull the codes

It means the battery is weak or you have a bad connection like Wes said. After checking those two, then I'd venture to replace any parts.

Thanks for the replies guyz....

Tell me,,,, is it bad ? or simple small repair(s) ?

No not bad. Easy things to check before spending money. If your battery is more than 2 years old consider just replacing it. A weak battery or one with a bad cell can cause all kinds of problems.
