To the best of my knowledge...No.(as long as you are counting all parts of "A" as a single "tileset" instead of 5 working together)
Though you can take those ones with only a few tiles and combine several of them into one, you just have to remember to credit the one(s) who made the tiles the same as if you used the set as it was. Lining them up can be a pain though if you don't have a 32x32 pixel grid in the image editor you are using. The grid lines must be BETWEEN the pixels to show the borders, not on a pixel or your tiles will be offset and won't line up properly. Also, leave the upper left 32x32 pixel square completely empty, not even an opaque background. You will need to set that tile to a star passability in the database.
