Answer 1

You can create a method to populate the list on Form2 (I called it SetAllPeople):

public partial class Form2 : Form
{
    public void SetAllPeople(List input)
    {
        foreach (string s in input)
        {
            lsbResidents.Items.Add(s);
        }
    }

    public Form2()
    {
        InitializeComponent();
    }
}

and then call Form2 this way:

Form2 lista = new Form2();
lista.SetAllPeople(allPeopleSource);
lista.ShowDialog();
