How can I do a program that when I push the boton 1, then boton2, then boton 3, turn on a LED conected in digital port.

You need to keep track of whether or not each switch has been pressed. If the order matters, then you need to reset when a switch is pressed out of order.

But how I keep track of whether or not each switch has been pressed.

But how I keep track of whether or not each switch has been pressed.

boolean swOnePressed = false;
boolean swTwoPressed = false;
boolean swThreePressed = false;

void loop()
{
   int swStateOne = digitalRead(swPinOne);
   int swStateTwo = digitalRead(swPinTwo);
   int swStateThree = digitalRead(swPinThree);

   if(swStateOne == HIGH)
      swOnePressed = true;
   // Repeat for other switches
}

If the order matters, you need to test each swXxxPressed variable before setting the others.
