I think you are probably correct with your ID of the first as Xerocomus rubellusHortiboletus rubellus
I don’t think you have X.chrysenteronXerocomellus porosporu
The cap crazing showing in your photo is very typical of that species (and will become more properly “cracked” as the caps age).
There seems to be some differences of opinion (within ID guide books etc.) as to the extent of the reddish area found on the stipes of X. porosporus
Some literature suggests that the red area will be a fine band near the apex, some will indicate quite an extensive area of red in the top half of the stipe, and some will indicate that the stipe below the red areas will be sepia toned.
All references seem to agree about the thin yellow band that will be seen above the red area, at the very apex of the stipes.
I’m not sure about the final one. I don’t think the cap is showing what would be expected of a fully mature X.rubellus
As with almost all boletes, cutting the examples in half through the cap and down the stem can give some good indicators such as what the inner flesh looks like, any internal red areas etc, and whether the sample “blues” or not, which areas, if any, do turn blue, and how long it takes to turn blue, etc. etc.
And, as I do with most ID reply suggestions, I’d add the usual caveat that microscopy would give the most certainty when macro characteristics alone leave some doubt.
