Corrosion of marble (a form of metamorphic limestone) is not a stain, but rather a dissolving of the base rock.
The solution (if not too deep) might involve surface grinding, honing and polishing in place, but is not a DIY project. Discuss with a marble installer/fabricator.
Another solution (if the marble tile is available) is to replace the one tile. ...

You would normally clean marble with etch spots with hydrogen peroxide or bleach and then repolish. From the sound of it yours may be more severely damaged. I would try both on a small spot and see how it goes.
If your marble is actually corroded then you will have to polish until you hit uncorroded marble.

Just paint the ceiling and add pot lights. I have finished a few basements like this and it looks great. Actually the only negative is the sound barrier a ceiling would give you and this can still be done with rigid foam sheets.

You didn't mention the type of home you have, but assuming it's a colonial style home, it wouldn't matter if your "basement" had 10' or 6" ceilings, as it would never be considered living space.
It would simply be viewed, and calculated as "finished" space, but never included as part of your "living space" calculation.

Do you just want to consolidate the loose surface stones for walking/tool storage?
If so, a concrete resurfacing mix, spread with a floor squeegee, will make a nice, smooth surface.
Understand that the underlying loose mix won't support much more than foot traffic (people walking on it) and the resurfacer may crack if overloaded.

Disclaimer: I'm not a scientist or an engineer, so it's entirely possible that all of this is wrong.
For the last part of your question regarding whether the insulation you used was too thin -- extruded polystyrene typically has an R-value of 5 per inch.
Here's the part where it would be great if someone who knew "the maths" could help me out. I've ...

A very important factor in deciding to use a thermal mass to store energy is the energy source. Solar energy is the classic example. The energy is free and the supply is periodic and unpredictable. Energy storage is a must.
You mentioned a boiler, so you likely are burning fuel, directly or indirectly, or at least paying for the supply. In this case, energy ...

The difference is in the use of your system and your personal preference.
Since you have insulated the ground beneath your slab, concrete thermal store can work in your favor.
Do you live in an area with consistent heating needs?
Embedded in the concrete will take a long time to heat the slab, this will be continuous circulation time... and it will stay ...

The epoxy paints are not really an epoxy. A real epoxy would have an activating ingredient. This designation is fake marketing. I do suggest you get a paint that is suitable for garage floor installation. The problem with painting a basement floor is the ease of scratching because usually you have metal storage things.
Yes to #2 because constant ...

Actually the most structurally sound fix would be to fill the hole with something solid. A snug bolt and nut would work. I also agree that this 1/2 inch hole is not effecting anything.

Replacing them? Getting an engineer? For a 1/2 hole in at least 8in joist? Seriously? I mean I'm sure the joist has lost some percentage of its strength. Like pretty small percentage. I would speculate that the lost strength is within tolerance limits for wood, which is not uniformly perfect. Unless you plan on having sumo wrestlers fight on top of those ...

This is a film sealer, as opposed to a penetrating sealer (bare concrete, grout). I know of no solvent/stripper that will remove an acrylic finish that won't remove (or damage) a latex undercoat.
I would try a reverse progression of grits, until you get to the paint. You may need to wait weeks for a hard enough/dry enough sealer surface. Start at 600 ...
