Does button 1, 2 and 3 need to be created indiviually to add in Actor 1, 2 and 3 respectively or i can just use SimpleActor to add in button 1, 2 and 3 to add in Actor 1, 2 and 3 repectively Example: Button 1 adds in Actor1 Button 2 adds in Actor2 Button 3 adds in Actor3 ect.

Both ways are possible. Using SimpleActor to create all buttons is easier to code.

but if i were to press button 1, button 2 and 3 won't be triggered even when they're all under the SimpleActor class right?(I want it to be that way)

Mouse clicks are on instances, not on classes.

it seems like I couldn't get the object reference right while using the mouseClicked() method... how do I refer the object for the mouseClicked() method? this is the code I'm using for the mouseClicked() Method:

Remove the switch in the act method. Just keep the if statements.

May I ask what is the switch statement mostly used for?

It is used to take only one of many possible options (or none). For example, if you had multiple type actors and you wanted to put only one, but randomly picked into the world, you could have this:
?
1
2
3
4
5
6
7
8
9
10
11
Actor actor = null;
switch(Greenfoot.getRandomNumber(800)
{
    case 0:  actor = new ActorA(); break;
    case 1:  actor = new ActorB(); break;
    case 2:  actor = new ActorC(); break;
    case 3:  actor = new ActorD(); break;
    case 4:  actor = new ActorE(); break;
    case 5:  actor = new ActorF(); break;
}
if (actor != null) addObject(actor, Greenfoot.getRandomNumber(getWidth(), 0);
This would add a random actor somewhere at the top edge of the world an average of maybe one every two seconds or so. Most of the time the switch block will end up doing nothing, keeping actor set to null.
