I wish you a nice day I have a number of labels inside windows form, for example with these names label1, labels2, label3, labels4 ... and so on

How to create a for loop to make changes to all or some of them properties according to a condition that depends on the number inside the label name

You can use the Label.Text property on each label to get and set the text on them.

To iterate through them just place them into a an array or list.

For example we can do

private Label label1;
private Label label2;
private Label label3;

void DoSomethingWithLabels()
{
    Label[] labels = { label1, label2, label3};
    
    foreach(var item in labels)
    {
        if(item.Text == "SomeText")
        {
             // do something
        }
        else
        {
             item.Text = "Hello World!";
        }
    }
}

Try this

        Label[] teste = { label1, label2, label3, label4 };

        foreach(var label in teste)
        {
            label.Text = "ALTERED";
        }

Assuming it's Windows Forms, and assuming the label names all start as "label", you can use the Form.Controls index property to get the labels. So you could loop like this:

for (int i = 1; i <= 3; i++) {
    var myLabel = this.Controls["label" + i.ToString()] as Label;
    //Do stuff with myLabel
}
