Looks like the same technology as the essentially-identical Sony product (or maybe even a simple re-branding of the Sony version?)
Notable by its absence was the specification for latency (always an issue with Bluetooth which was not designed as a “real-time” delivery protocol). -
As you said, audio LEVELS are measured in db (deciBels) or volts (or millivolts).
But audio FREQUENCY is measured in Hz (Hertz).
If you look at those on (for example) a frequency-resposnse graph, typically the X-axis (horizontal) dimension is frequency in Hz, and the Y-axis (vertical) is measured in dB.

There is no generic answer to your question. It is quite possible that will work fine. But it depends a great deal on what kind of connection you have and what is being used at the other end of the conversation. If you are talking to the same person at the other end, then you presumably have some amount of control or at least influence over the configuration. But if you are accepting annonymous call-ins from the unpredictable general public, that is a different matter. The acoustics at the other end influence the quality of your recording, and the quality of the link echo-cancelling can make or break a setup.

JK Audio makes a range of telephone interface products for basic interfacing. Note that you will probably need an old-fashioned analog telephone line (POTS = Plain Old Telephone Service). But they even make Bluetooth products to tap into cell phones, etc.

There are solutions ranging from essentially free to several thousand dollars. Depending on what issues you need to solve, what is your budget, what is your level of quality expectations. etc.

“Would using the mixer in the chain reduce the noise floor on the recordings when compared to directly recording to the h6?”
It probably wouldn’t be of much benefit for the wireless receivers. You can crank them up to a good level to maximize the signal-to-noise ratio in the H6.
Only YOU can actually do the experiment to see whether using the mixer would improve the performance from the ME65 or other source(s).

The SQN-4S_mini mk II has individual, pre-fader line outs from each of the four channels. Apparently the original version does not have this feature and you can get only the 2-channel mix out of it. We don’t know whether you have the original or the MK II version, so only you can answer that question.
Unless you have the MK II version of the mixer, you are limited to a 2-channel mix. Plugging all your mics directly into the Zoom H6 would give you separate tracks for each mic. Unless you are mixing down everything live as you are shooting (good luck with that), then it is not clear what benefit your mixer will be (unless it is the MK II version).

In very similar situations, you will note that most fitness trainers use headset microphones which work quite well even when performing vigorous exercise routines. Highly recommended.

It sounds to me like your kit is simply broken. An antenna connection is broken internally (severely limiting the amount of RF transmitted or received). Or either the transmitter or the receiver frequency or RF tuning circuits are no longer aligned to properly communicate with each other. Or several other things that could be wrong.
Of course, we are assuming that you are performing the tests with NEW, and KNOWN GOOD batteries. Not batteries you bought from some place that have been sitting on a dusty shelf for a year. NOT RECHARGEABLE batteries of any kind!!! Good, name-brand primary cells. A rechargeable battery, even when FULLY CHARGED only has the terminal voltage of a nearly-flat primary cell. Whether we like it or not. Most wireless kits perform terribly with rechargeable batteries.
The symptoms are those of simply “signal starvation” where the receiver is not getting enough signal from the transmitter to support a good, noise-free connection. This could be a problem with the transmitter. Or it could be a problem with the receiver (or even both). With only a single kit at hand, you have very limited options for troubleshooting.

Your sample file URL doesn’t work.
Noise that happens as the transmitters move around is not caused by cell phones or interference. It is a simple RF propagation problem.
You never mentioned what kind of working distance you are trying to use, so we are unable to evaluate that major factor.
It seems possible that the transmitter or receiver have drifted so they are not properly tuned to each other. Or an antenna may actually be broken insternally even though it looks OK on the outside.
