Combos are always made of two shops and a decoration, and they usually follow the theme of a particular kind of house. If you want to see all of them which are available, browse the decorations: the comments under them tell what two shops the decoration makes a combo with. If you don't see any more, it may mean you need to level up a little to unlock some new ones.
