An inductor just shows the resistance of the coil wire or trace at DC, and a very low resistance is not unusual with some types.
Commonly the higher the current they are rated for, the lower the DC resistance to minimise resistive power losses.
A good diode should show open circuit in one direction and continuity with a voltage drop (often around 0.6V) in the other direction.
It may give a reading on a resistance test but that depends on the meter. You may need to use a specific "diode test" range to get a sensible result.

With capacitors, there is nothing wrong with the values you give. Low ESR is good!
The other important value is the actual capacitance they measure at, which you have not given.
Also, any obvious visual defects, such as leakage or the casing starting to swell. #3 looks as if the top is bulging slightly?
If all of that style are the same, it may not mean anything - but if others have flat tops, it's probably an indication the cap is degrading.
