I broke an SMD ceramic capacitor : r/laptops

It could be important in ref design, but not in full circuit. So, I would say, it can work even without that capacitor. And u should not try soldering small smd componets with no exp, u can overheat, damage or do smth else to the board. And that capacitor can be damaged already, so u soldering dead cap aka wasting time. So use it as it is.

What happens when a ceramic bypass or decoupling capacitor

Too much voltage can also cause the capacitor to flex, resulting in a stress crack. Then you get the same result as above. The capacitor becomes more like a resistor, or shorts out entirely - bang or burn. Neither failure mode is usually a problem. Stay under the rated voltage, don''t bend your PCB or hammer on the capacitors and you should be fine.

Identifying 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.
