Different LED light patterns, One Button

Other Hardware LEDs and Multiplexing
1

I have a code that flashes a pattern with 5 lights when I press a switch. I would like to add a few more patterns that would happen the next few times the button is pressed. For example, have a code that has one pattern the first time it's pressed, have a different pattern the second time the button is pressed, and then have one more pattern the third time is pressed. The fourth time, I want the first pattern to occur again and the fifth time, the second pattern, and have this continue. What would I use in the code to achieve this? I'm new to Arduino and am just using this for an art class. Please help! Here is my code:

int switch1 = 0; //button

void setup() {
pinMode(5, OUTPUT);
pinMode(6, OUTPUT);
pinMode(7, OUTPUT);
pinMode(8, OUTPUT);
pinMode(9, OUTPUT);

pinMode(2, INPUT); //Switch
}

void loop() {

switch1 = digitalRead(2);

if(switch1 == LOW) {
// when button is not pressed:
digitalWrite(5, HIGH);
digitalWrite(6, LOW);
digitalWrite(7, LOW);
digitalWrite(8, LOW);
digitalWrite(9, LOW);

}

else{
//when button is pressed:
delay(600);
digitalWrite(5, LOW);
digitalWrite(6, HIGH);
delay(600);
digitalWrite(6, LOW);
digitalWrite(7, HIGH);
delay(600);
digitalWrite(7, LOW);
digitalWrite(8, HIGH);
delay(600);
digitalWrite(8, LOW);
digitalWrite(9, HIGH);
delay(2000);
digitalWrite(9, LOW);
}

}

You could use a global called iMode which goes from 1 to 3.
When it reaches 3, set it back to 1.
You do this every time you push the button.

What is a global and what is iMode? Is it something that goes into the code? If so, how would this be written?

A global variable is one which is declared outside of loop() or setup() or any other function, and so is visible and can be used and updated from inside any function. iMode is a suggestion of a name that you could give that variable, but you can call it anything you like. You already have an example of a global variable in your code called switch1.
