"OL" on your meter literally means "overload" but in the contect of resistance means open circuit, or a higher resistance than the meter can measure. So the 0A70 is definitely duff.
A 0.01uF cap will never be an electrolytic. It will be a paper dielectric. Replace with a modern 0.01uF part. Commonly called 10nF these days. Any plastic dielectric (polyester, mylar etc) part will be fine. The high capacitance readings are caused by the caps being leaky. It's a side effect of the measurement method used in low cost meters that leakage shows up as high capacitance.
Rule of thumb: Most capacitors of 1uF and above will be electrolytic, most below that will not. The smallest electrolytics I can recall were 0.47uF which I would normally replace with plastic non-electrolytics. You can commonly get non-electrolytic caps up to 10uF. Even higher for some purposes.
