Despite many components these days being SMD (including electrolytic capacitors), through-hole aluminum electrolytic capacitors are still used. One of the reasons for this is that the physical size of a capacitor is often proportional to its capacitance and so capacitors greater than 100μF will be too large to be an SMD …

Contact UsIdentifying an unmarked SMD capacitor and chip
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.
