Hello crystal246 and welcome to the community.
The photos you used are a pretty basic and simple enough to do but you must remember that if you are in an apartment they must be small enough to fit through the door. There are several ways to go about this.
Since you need them to be portable one possibility would be to construct several narrower panels to the desired height and install them in a slotted base so they can be broken down and moved. Another way would be to again create your panels and fix them to each other using hinges that open in alternating directions and it would stand on its own like regular room divider.
You may consider pre-built room dividers as seen here on the Home depot web site. There is quite a variety of style. There is one model divider that also is a bookcase. Another you can mount photos on and has a mirror as the center panel.. See a few in the following photos.
With more information on your dimensions and your building experience, I could come up with other suggestion. Please keep me informed.
Thanks for your inquiry.
