You can also use grid cubes..this will again depend on the size and weight of your plants.
This one I have outdoors, but it can be used indoors. The grid can be reconfigured in whatever style you like, can be upright, or horizontal or corner, depends on how many grid panels you have: you will just have to put some saucers on each plant to catch excess water.
Or you can try and use multi-stacking containers, I use this outdoors, but it can be good for herbs, and smaller succulents, placed near a window:
