Personally, I think you may have a hard time finding 5 matching stands in different heights, but I have 2 suggestions:

(1) If you're DIY-inclined, head over to your local thrift shop (e.g., Goodwill) and pick out cake stands of similar styles. You could probably find cookie trays too, but not likely 3 matching ones. Spray paint them a matching color.

(2) If you're not DIY-inclined, get ready to search Amazon, Target, Michaels, and Joann with a fine-tooth comb. Pick a color you like and search for "X + cake stand":

• Lace: Cake stand that comes in two diameters, both different heights + similar low cake stand + rectangle stands
  
  
• Silver: Cake stand + another cake stand + etc., etc.
