help…how to draw a rectangle over “holes” without closing them

You have to make the thing with holes into a component. Select the entire item by drawing a left-to-right box around it with the Select tool, then type the letter G. Name the component and click the Create button. Then you can draw a rectangle over that thing without closing the holes.
Are you trying to create four edges with no surface between them? If so, the previous post is good advice but you will have to delete the surface which is automatically created whenever you draw a closed loop.
BTW, you seem to have a lot of reversed faces.
