    private static Form1 inst;
    public static Form1 GetForm
    {
        get
        {
            if (inst == null || inst.IsDisposed)
            {
                inst = new Form1();
            }
            return inst;
        }
    }
    public Form1()
    {
        InitializeComponent();
        inst = this;
    }

    private void button1_Click(object sender, EventArgs e)
    {
        Form2.GetForm.Show();
        this.Hide();
    }
}

public partial class Form2 : Form
{
    private static Form2 inst;
    public static Form2 GetForm
    {
        get
        {
            if (inst == null || inst.IsDisposed)
                inst = new Form2();
            return inst;
        }
    }
    public Form2()
    {
        InitializeComponent();
    }
    private void button1_Click(object sender, EventArgs e)
    {
        Form1.GetForm.Show();
        this.Hide();
    }
    private void Form2_FormClosed(object sender, FormClosedEventArgs e)
    {
        Form1.GetForm.Show();
    }
}

if you have more than two form then create another form as From2
