The property MDIChildCount will give you the number of occurrences of children.  This is assuming that you've correctly made the parent form property FormStyle fsMDIForm.  Here's some example code that closes all the MDI children of Form1.

void __fastcall TForm1::Button1Click(TObject *Sender)

{
  for(int i = 0; i < MDIChildCount; i++)
    MDIChildren[i]->Close();
}
