My problem is How to show Modal Forms at the same time:
when 1st form unloaded, the second is also modal
form, .....

You have to call the new form's show method from the previous form ...  you
can't just put a series of modal show commands in one event since execution
suspends until the first modal form is closed. I.e...

'in form 1
command1_click
   form2.show vbmodal
end sub

'in form 2
command1_click
   form3.show vbmodal
end sub
