It seems the odd lens in your list is the 10-22, all others are pretty much wide to short telephoto. The 10-22 is a fantastic lens, covers 16-35 in FF, it's distortion is well corrected and fairly easy to manage in post. There's no doubt on a crop body it is one of the best ultra-wide to wide zooms on the market. And with your 17-55, even with the small overlap, would make a great addition to your kit...IMHO
I shoot film and used the 20-35 for years, was quite happy as my skills below 20mm simply sucked. But after getting the 10-22 and discovering the ultra-wide's benefits it became clear that I could also successfully use a FOV below 20mm. Looking at the price tag on a 16-35, I turned to the 17-40L; for film duties, and it makes for a usable walkabout wide-to-normal zoom, shorter then your 17-55, but quite usable, so keep your 17-55.
In near 40yrs of shooting the walkaround zoom hasn't been used as much as the ends of the ultra-wide to medium telephoto FOV. My typical day bag has an ultra-wide zoom, 100 macro and 70-200 zoom. Fast 28, 50 and 85 primes are added when required.
I do quite often carry an old, much used, canon 24-85. It was stuck on one of my EOS-3 film bodies for years and gets a digital workout when out on a casual day shoot. Sometimes those mid range 'do it all' zooms are extremely helpful. It's a USM f3.5-4.5 zoom that's near the same size as the 85 f1.8, and is quite handy to have around.
I don't do a lot of low-light/night shooting so fast f2.8 lenses are not usually required. Since 07 I've shot digital crop bodies exclusively, but will add FF; the 6D, this year. Even though FF is my ultimate goal, I don't see myself without a crop body and that's why the 10-22 was an easy decision. It's the only EF-S lens I ever see buying as all the other EF lenses cover everything else I need.
As others have said use what you need today. Lenses don't depreciate that much, resale for the higher-end EF-S lenses is a good bet. Even a few hundred dollar loss is no more then what a rental fee would be.
I'd add a used 10-22 to your kit, shoot with it for 6 months to a year, then look back at the shots you took and determine if the ultra-wide FOV filled a gap you really needed. Then look at your least used lens; Lightroom has a great FL/Lens search feature, and if it didn't produce any or only a few keepers, sell it if you can do without it.
Best of luck on your lens choices...
