Legal? 7 breakers for one outlet?

Using what’s available/existing, I did this wiring, and am wondering how many codes I violated. I over stuffed a conduit probably, but the following number of breakers may be concerning:
- 200 amp outdoor shutoff breaker/switch
- 200 amp main panel breaker/switch
- 90 amp breaker for garage in main panel
- 100 amp breaker in garage 16-slot subpanel
- 20 amp breaker in garage subpanel to feed old 2 slot breaker box (that old GFCI breaker fits in)
- 20 amp GFCI breaker to feed a 20 amp outlet, AND the following 15 amp breaker that’s right next to the 20 amp GFCI.
- 15 amp breaker fed by above GFCi breaker to feed 14 gauge wires for lights and an outlet.
It seems insane, but it works (for now).

Is this too many breakers? 1) 200 amp outside service shutoff 2) 200 amp main panel breaker 3) 90 amp garage subpanel breaker in the main panel 4) 100 amp breaker for the garage subpanel 5) 20 amp breaker for the circuit that feeds the 2-slot panel 6) 20 amp GFCI breaker 7) 15 amp breaker for the lights and single outlet..
