	  1. give each one an ID (ID_RB1,ID_RB2,...ID_RB5)
	  2. in the DlgProc for the dialog box, handle the messages
	     as follows:
		case WM_COMMAND:
		  id=(int)wparam;
		  switch(id){
		    ID_RB1:
		    ID_RB2:
		    ID_RB3:
		    ID_RB4:
		    ID_RB5: CheckRadioButton(hdlg,ID_RB1,ID_RB5,id);
			    break;

	You should not use radio buttons for this type of selection.
	Use checkboxes instead.  If you use BS_AUTOCHECKBOX, then
	the control will check & uncheck itself.  You only have to
	'read' the settings when you press OK to terminate the
	dialog box.  Here you will want to use IsDlgButtonChecked().

BTW, most of this stuff is in Petzold's "Programming Windows 3.1"
which is essential.  If you don't have it, get it.
