user6891: I need to read 5 analog pins simultaneously , is it possible?
note that: 
analogRead(1); 
analogRead(2); 
analogRead(3); 
will not work this case

user368: No, it is not. The ADC in the MCU is only capable of sampling a single analog channel at a time.
If you require sampling more than one channel at a time then you will need to use one or more external ADCs that are capable of sampling multiple channels, or multiple ADCs each dedicated to a single channel.
