surface mount
Those are plain multi-layer ceramic capacitors and are bipolar, or rather non-polarized.. The reason you are getting odd results is that you probably measure the capacitance while they are soldered into a circuit. This means that you have a number of unknown devices in parallel to the capacitor, so the result can be pretty much anything.
How to Identify Capacitors
