You should use a timer, Set the Interval to 5000 milliseconds which is 5 seconds and enter this code under the Timer_Tick event

'Declare a variable for storing the current index
Dim index As Integer = 0
Private Sub Timer1_Tick_1(sender As Object, e As EventArgs) Handles Timer1.Tick
    If (Not index >= RichTextBox2.Lines.Length- 1) Then
        txt_myip.Text = RichTextBox2.Lines(index)
        index += 1
    Else 
        index = 0
        Timer1.Stop()
    End If
End Sub
