Can you scrape it off?

the last picture looks like a fungus. the second picture looks like it could be scale...if it can be scraped off.

This leaf on the Pot of Gold as me a little concerned about fungus. The back of the leaf looks fine

I have some kerriis that I bought from a nursery that closing down. They all had those fungus spots. I gave them drier conditions with air movement and they are improving.

wipe off what you can, then cut it back a bit and it should re grow healthy.

What Lydia said, every single variegated kerrii I've see has those spots. (like the last photo) They spread :( My last resort is cutting them off, even if it means chopping a leaf in half.

I was able to scrape off the scale from the Verticillata as well as others found on the undersides of other leaves.

Do the purple spots look like humidity spots or previous pest issues that could have lead to a fungus (and hopefully not a virus) or maybe it's just ugly cosmetic blemishes due to living outdoors in FL?
