Query Strings & Custom Tax show in Cloeset furthest

Hiya guy’s Gals., Lil help please if possible

Am having troubles trying to work out what to use. I looked at the doc’s page and still could put together the code I need for the Carousel

Wanting a certain Custom Tax to show closest to furthest inside a Carousel. I got the Closest to furthest bit correct

And can I have multiple custom TAX within that sting, or just one, using XXXX’s in replacement of code

I have a page For Disabled Person, a Page for Elderly, a page for others.

Each page will have the corresponding TAX order by closest to furthest in a Carousel
