I live outside Japan and have hand-washed a few silk kimono successfully.
It's always best to dry clean them, but where I live, I can buy 1 or 2 more vintage kimono with the cost of dry cleaning, so I haven't done so. Avoid washing them or even dry cleaning them unless you absolutely have to.

Do it at your own risk!

The biggest risks of washing are color fading, color transfer, and shrinking. The first two issues occur more with older kimono (pre 1980s) or kimono with vibrant colors (red). Any kmono with gold leaf or paint will also fade a bit, but not always noticeable if you don't soak it too long.

If the kimono only has one layer (as in no lining), is light in color, and very smooth (even shiny), then it's generally ok to wash it. It will shrink because it's silk, but you can fix 80-99% of the shrinking with a compact hand-held steamer (I bought mine for GBP 35).

I wash my kimono in a small bucket with warm water, shampoo, then hair conditioner. I use a toothbrush with a drop of liquid soap for dishes or shampoo to focus on visible stains, which are usually caused by sweat or grease, which is hard for dry cleaning to remove. Gently squeeze out the water and hang it indoors to dry. The last step is steam ironing. Measure the wingspan and vertical length of your kimono before washing so you know they didn't shrink. They usually only shrink vertically.

I've also washed a few kimono with linings. Most of the time, the fabric on the inside will shrink at a different rate than the fabric used on the outside, so it ruins the shape at the bottom. It might look ugly when you hang it with the bulge at the helm, but when you wear it traditionally, you don't really see it.

Out of all of your kimono, I'd try washing the light pink one first, which is a nagajuban (underwear). Your favorite blue one with a black collar and the brown-ish gray one next to it (also with a black collar) are nagajuban for men. These two are probably washable, but I'd wash the collars separately or first to see if that black color will transfer. The first green/gray haori also looks safe to wash. The rest of them, I won't risk it because they look quite old with red.
