Three ceramic stars, one red, one blue, one yellow. These just seem to float from place to place on the fridge, never really being pressed into service.
One ladybug. Ditto.
Two stainless steel “knobs” that could probably each lift a car, and are nearly impossible to peel off the fridge. The only way I can pry them loose is to make sure that under each is a good 1/8 thickness of paper. One holds report cards and progress reports for the entire school year, the other has medical bills under it.
Three reproductions of vintage advertising: Cracker Jack, Dutch Maid Scouring Powder and “Pepsi 5 cents.” They don’t do anything either, but they sorta match the decor of my kitchen, which is a hodge-podge of vintage general store combined with 50s ice cream parlor.
Two flat flexible calendars from school (one from last year… I oughta go through these more often). Also, one calendar cum notepad thingie from my Realtor, also from last year.
Two radio station flat flexible magnets that hold recipes on the “non-public” side of the fridge (the side that is almost blocked by the pantry.)
Two black plastic spring clip things that hold coupons and miscellaneous things - sometimes a dishtowel.
A cardinal made out of a clothespin and some Fun Foam and googly eyes that my daughter made in third grade. It’s supposed to hold papers, but the magnet is so weak that anything heavier than a single coupon causes it to slide UNDER the fridge, so mostly it just sits there, barely clinging.
A puzzle magnet from Amazon.com. The outside of this one double as a picture frame and is currently hosting a photo of my daughter, her friend and me at the zoo. The inside is an animal jigsaw that has pieces scattered all over the non-public side of the fridge and one piece on top of the fridge because that irritates my daughter 
A polymer clay thingie that a friend bought me. It says “Friends are flowers in the garden of life” and it’s a TERRIBLE example of quality polymer clay work, but a nice thought just the same.
That was kinda fun! I should do this more often.
