For the plasterboard wall buy a small sheet of plasterboard and glue sections into the holes (once you've tidied them up). Once the holes are filled do the final surface with filler.
For the other wall, I'd use plaster. I'd also cap over that cable first.
I'm sure there'll be videos showing how to fix both of them on YouTube if you look.

For the browning chase, I would use what came out. Browning / Thistle. Let it go off for 24 hours, then plaster with a finish coat.
The plasterboard, I would trim neatly, fix plasterboard or timber behind the existing board, then infill and glue with a piece of plasterboard to match and finish with a slim coat of ready mix plaster.
Sand to finish.

For the browning wall I'd use plaster board adhesive followed by a surface filler to finish. The adhesive dries really quick and shrinks slightly leaving room for a thin top coat of filler you can easily sand for a seamless finish. It's a tried and trusted solution for electricians.
For the plaster board wall glue in bits of plasterboard skin overcwith filler and sand job done.

As a non-builder and non-plasterer, I don't have the usual tools available (mixing tool, etc) so I would ideally opt to use ready-made products. Would this impact on the finished result?
Something like using the plasterboard adhesive here: https://www.screwfix.com/c/sealants-adhesives/plasterboard-adhesives/cat9780001
And then fine finish ready-made plaster such as that here: https://www.toolstation.com/fill-skim-ready-mixed-lightweight-plaster/p44295
As for the plasterboard holes, I'm reluctantly going to have to locate some plasterboard and cut it up it seems. Any tips on securing it as there is around a 2" airgap behind the current surface and the breezeblocks?

Have a look at this https://www.youtube.com/watch?v=8X3__7RMgMQ
Mixing small amounts of plaster or adhesive doesn't need any special mixing tools.

Put in a few bits of strip-wood screwed in with plasterboard screws and then secure your new patch piece to those strips. Reskim then paint. If you really want to go the extra mile then taping the seams would help prevent future cracking. Make sure you use a joint compound or other suitable repair product as it resist shrinking.

I had to do similar.
Get some plaster board off cuts, make them slightly smaller than the main hole. Then I used grip fill, a decent splodge round the edge and squeezed them into place. Slowly pushed the board with a large piece of wood (that overlapped the area), this pushed it further in to the point the main in fill was level with the wall. gently removed any that had sqeezed out the front with a filling knife and left for 24 hours.
It was almost perfectly level, so just left the small areas to fill with normal filler.

As recommended by everyone, I ended up using plasterboard screws to screw in a smaller bit of drywall to the breeze block, then used filler around it.
Random orbital sanded it until no discernible lip or join to the touch, few licks of emulsion paint, and now just needs final coat of vinyl matt.
The proper browning chase is completely filled just needs random orbital sanding and then painting :
