Added in edit: I wouldn't have expected the inductors to be measured very accurately because the measured value depends on the level of the voltage applied to them and the temperature.
I also see that I made a mistake in the ESR of the little blue 26 mH inductor. The ESRs should be in k ohms, not ohms. In other words, the ESR at 1 kHz is not .109 ohms, but rather 109 ohms.

You could add a k on the tape.
The measurement of the capacitance of the red box cap looks to me to be about .1%, not .5%

I think the problem with the red cap is that I forgot to mention that the ESR numbers are in milliohms, not ohms.

Looking at your images, I see that at 1 kHz, you got .04 ohms for ESR, which is pretty close to the .057 ohms I got.
At 100 kHz, you got .200 ohms for ESR, whereas I got .0055 ohms. I don't have a ready explanation for that except that polycarbonate caps have a very low ESR at high frequency for their capacitance. It's a difficult measurement to make. Why don't you try making the measurement at 100 kHz with your meter in Rs mode?
Here's an image of a frequency sweep showing Z and ESR for another of those red box caps:

You can see that the ESR gets quite low at high frequencies.
