Make one part for each sticker. The part is the exact size of the sticker and has some small thickness. Then go into the appearance manager and attach a jpeg of the actual sticker to the surface of the part using the decal option.

The sticker parts can then be assembled onto the surface of the model where they belong.

Also, the jpegs need to be in the working directory to get loaded automatically when you open the model.
