By using the class name you are referring to the default instance and there is only ever one default instance at a time. If you want multiple instances simultaneously then you need to create them yourself.
For i As Integer = 1 To 5
Dim f2 As New Form2
f2.Show()
Next
You might like to check out my blog post on the subject of default instances to learn more.
By the way, you can also combine the two lines within that loop into one, but note that you cannot start a line with the New keyword, so this is one of the few times that the Call keyword is useful.
For i As Integer = 1 To 5
Call New Form2().Show()

You need to create new instances.For example:
For i As Integer = 1 To 5
Dim frm As New Form2
frm.Show()
Next
In case you need to access those instances you can keep them in a List
Dim forms As New List(Of Form)(5)
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
For i As Integer = 1 To forms.Capacity
Dim frm As New frmBaleRevision
forms.Add(frm)
frm.Show()
Next
End Sub

You can do with this code and change the properties of each form (in this example it gonna be the text of the form):
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
For i As Integer = 1 To 5
Dim x As New Form2
x.Text = "New Form " & i
x.Show()
Next
End Sub
