For those familiar with IUPAC from Organic Chemistry, (CH3)2CHCH2CH2Br would be named 1-bromo-3-methylbutane and there is zero ambiguity (1 singular IUPAC name cannot refer to 2 different molecules) because organic chemists absolutely require a naming scheme that is unambiguous and that other chemists can reliably follow to derive the same exact name (in this example of 1-bromo-3-methylbutane).
I took 1 music theory class 20 years ago and if I recall correctly, the sequence of notes (from lowest to highest pitch) is irrelevant and also duplicates are irrelevant. In my diagram, the 4th chord (chord 4) has 4 unique notes and 2 duplicates. Here are my first three questions:
Do these 4 unique notes (Bb, C, Eb, G) always have the same chord name? Does the key matter? Do the nearby chords (or sequence of chords) matter?
According to Quora:
What would you call the chord made up of (C, Eb, G, and Bb)?
This is a C Minor 7th (not a C Minor Major 7th as some have suggested, as here we have a Bb not B) ¶ Minor 7th Chords are made up of the Root, Minor 3rd, 5th and Flat 7th. In this case, C is the root, Eb is the minor 3rd, G is the 5th and Bb is the flat 7th. ¶ Minor 7th chords are the minor equivalent of a Dominant 7 chord, which uses the flat 7th also (C7 uses C, E, G and Bb). ¶ Hope this helps, ¶ Rob
I am currently watching a 12-episode playlist on YouTube by MusicFraser titled "triads and chords" and I'm on the 4th episode (Augmented Triads) which is what sparked my question. My curiosity stems from the fact that it's plausible to add an additional high-pitched note to an "established chord" (such as adding a high-pitched note onto the the tonic of a highly-predictable ending cadence such as I, IV, V, I and it can technically change the final chord from a "I" to a completely different chord?)

Fourth and final question: Is "2a" a different chord than "2b" because the "A-note" drops down to a "G-note"?
Or is the "G-note" from "2b" added to the 5 notes of 2a to form a 6-note chord?

TL;DR: Is there a "systematic method" to unambiguously name chords that have 4 or 5 notes similar to how Organic Chemists use IUPAC systematic naming? 🤔
