Are these for plasterboard and solid brick/stone walls? Also I presume any faceplates will fit and not just Schneider ones?
Or does anyone have any other recommends?

They are for Placo.
The fixing centres of sockets and switches are standardised across all manufacturers.
My recommendation is to buy the deepest boxes that you can fit in your cloisons and to buy a holesaw preferably 1mm smaller than the size they recommend and wiggle your hips while drilling to open the hole out to a close fit.
Never ever use one of the split multi-holesaws, there is precious little material retaining a box within a cloison or preventing it from falling inside when you push the socket back against the wires to fix it.

When boring a hole in stone and cutting a groove for the gaine with an angle grinder and diamond disc, I fix the socket well in with a dollop of MAP. I also prefer the Legrand wells as they have a reasonable retainer device. This is when the wall is to be plastered. When building placo walls on a stud foundation, I install a wooden backing plank for the wells to screw them into as the grip from the retainer device against the back of the placo is sustantial, but these French sockets an plugs tend to be difficult to withdraw (worst design ever, schuko sockets locate the plugs so much easier). I have never found a choice of sizes of hole drills that allow to drill a 1mm smaller hole, these are standard drills (67mm I think). When boring stone, I use a drill that is a tube with the end covered in a diamond grit, no slots, and drill without percussion.

These are only for placo , you will need different ones for stone/bricks
" cloison plein "

I would not say they are only for placo, as the way I glue them in works just as well for these sort. It depends what I have lying around at the time as to which I install. If you go for the square wells, you can easier cut the hole with the angle grinder while also cutting the groove for the conduit, so make a bigger dust cloud.

"Also I presume any faceplates will fit and not just Schneider ones?"
Its only a back box so generally everything else in front of that should fit and be to the standard. Where you need to be careful is when using "modular" type sockets, switches, etc. Particularly when buying from discount brico sources. Their cheapest offerings are often of limited availability. In the past I bought boxes of items and found a year or so later there was nothing available to fit. This includes units that miss the mounting holes in most of the back boxes on the shelves. Try to buy everything you will need in one go and don't expect to find a matching item a year later.

Another option is a multi material box, it fits placo but also can be glue or screwed in stone etc.

I have never found a choice of sizes of hole drills that allow to drill a 1mm smaller hole, these are standard drills (67mm I think). I think you are right, I was using the cheapest of the cheapest as I had such a volume to do, the moulding said pércage 68mm, maybe even more, they are an interference fit in a hole bored with a 67mm bit wobbled around which is what I aim for.

Having only used Legrand back boxes we use a 67mm hole saw in placo and 68mm in wood or other hard substrates. Our hole-saw box contains all from 19mm - 127mm. DO NOT BUY CHEAP.

Tip. When sawing through placo with these round saws, when finished, brush of the plaster dust and wipe down with WD 40 to keep them from rusting, otherwise they will rust within a few days.

I have never had one rust in 17 years, maybe its your storage conditions.
Moisture and air are needed for rusting to occur, maybe the plaster dust is removing any protective oil film or rubbing through any existing benign oxidisation.
