That isn't the way timers work: each time you get a Tick event, you take a line from the RichTextBox and display it in your textbox, then set up conditions for the next Tick - normally by using a class level variable which holds the "next line number" to display.

Using a loop in th Tick handler doesn't do that, if always puts the content from the last line in the text box!

Get rid of the loop, and use a class level Integer as an index into the RichTextBox lines.

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
