Hi. Firstly, welcome to the forum. What you're calling "slots" we call 'combs'. Combs start off life as pure white, and then gradually darken with use - partly due to the propolis (tree-gum) which the bees line the cells with, and partly due to dirty feet. All brood combs eventually turn black - honey-combs tend to stay white or off-white for much longer.
The capped cells are brood (inside them are larvae transforming into young bees). Pollen is always visible, and never obscured by wax cappings in the same way as brood is.
Is your colony fine ? No. But, it's impossible to give detailed advice with so many bees obscuring the cells (as in the last photograph), however the photograph above it shows several dead pupae, which looks to me like a case of chalk-brood.
With the exception of the comb in the bottom photograph (which may be viable) the absence of both honey and pollen in the other combs indicates a colony in trouble, and which needs feeding (with sugar syrup) as a matter of some urgency.
A strong healthy colony is well able to fend-off wax-moths, and that you have already discovered wax-moth worms is further evidence that this tiny colony is weak and in trouble.
Of course you are very welcome to seek advice here, but nothing beats the assistance of someone local, who would be far more familiar with your local conditions - which is important.
At the very least, could I suggest that you gently shake-off, or brush-off the bees from the comb shown in the bottom photograph, and re-photograph both sides.
Also - as a matter of urgency - can you please supply that colony with some sugar syrup. Otherwise they will starve.
