I need simple code that execute for every 5 minute without delay and millis fuction,

Use "micros".
Five minutes is 300 000 000 microseconds, so make sure you use an unsigned long ("300000000UL")

And please, stop SHOUTING.

Have a look at the blink without delay tutorial, and substitute "micros()" wherever it says "millis()", and multiply the interval by 1000.
