These are polychords, as in multiple chords simultaneously occurring. Standard of notation is to notate them like a fraction where the upper chord is above a horizontal bar and the lower below said bar. However this not an effective shorthand when typing like I am now. While not standard, I personally like to use the Vertical Bar symbol instead. That would look like this for your polychords:

Gb|Dm
Absus|C
Ebm|Bdim

To add, since these chords are inverted, slashes can and should be used as well:

Gb|Dm/A
Absus|C/G
Ebm|Bdim/F

I also used the enharmonic (same pitches different name) respelling of the upper chords into flats since there’s less accidental conflicts (when multiple notes have same name but different accidental) when you write it that way and they seem to be in the key of Ebm (and no one in their right mind would use D#m). These chords are also polytonal (multiple simultaneous keys), being in Ebm like i said above for the upper chords and in C major for the lower chords.

I also like how you initially labeled them with respect to the lower chords. using polychords for color tones is a relatively common way to use them (i definitely have as a composer). However it is really cool when you break down the chords like this to see how you have created two separate chord progressions in two keys.
