how to separate visible form instances' locations - vb.net

Question

from a question here : Question
Dim forms As Collections.Generic.IEnumerable(Of frmMain) = Application.OpenForms.OfType(Of frmMain).Where(Function(frm) frm.Visible)
For Each f As Form In forms
f.Location = New Point(0, 0) ' set coordinate as needed
Next
UPDATE the above code gets all visible forms but since its generic, all the visible forms appear on one place..
let's say, I have 3 markers.. named camera1 camera2 camera3..
on Form_Load I will click those 3 markers, and a supposed video feed will appear (in this case, each with a new instance of form2)
this is my code in which does what I want, only problem is, I want it to be reusable for the future of dynamically adding more rather than this, predefined.
Dim f2c1 As New Form2
Dim f2c2 As New Form2
Dim f2c3 As New Form2
If f2c1.Visible = True Then
f2c1.Location = camera1.LocalPosition + New Point(20, -240)
End If
If f2c2.Visible = True Then
f2c2.Location = camera2.LocalPosition + New Point(20, -240)
End If
If f2c3.Visible = True Then
f2c3.Location = camera3.LocalPosition + New Point(20, -240)
End If
that code, is this.. If I click the marker, drag the map. video feed form2 stays with them.
I want it on a function or sub that will do this..
'Public Sub when I drag the map()
'every form visible
'will follow -- let's say, will follow what marker clicked them
ask me if you need anything.. thanks

I did some workaround
Dim mList As New List(Of String)
marker.ToolTipMode = MarkerTooltipMode.Always 'as an indetifier of each markers as
marker.ToolTipText = dtrow("MarkerName") 'I have added it to a for each
Try
For Each m In mList 'get items from the list
If item.ToolTipText = m Then 'check same name
Dim f As New Form2
With f
If .Visible = True Then
.Hide()
Else
.Show()
Dim p As New Point
p = item.LocalPosition + New Point(20, -240)
.Location = p 'after I click form will appear right next to them
.Text = m
End If
End With
Exit Sub
End If
Next
Catch ex As Exception
MessageBox.Show(ex.Message)
End Try
this is still not the ideal thing that is on my mind, but this practically answers my question for the moment.
