Today I went hiking to watch river flow, the S river and saw these guys. Could someone identify these Mayfly and some aquatic insect? (Maybe caddis larvae?)

I searched it and looks like! Attached more pics
The mayfly also could be Rhithrogena. I’m probably wrong and recommend asking in the entomology sub forum. http://www.troutnut.com/specimen/1084
In the water are cased caddis larvae, that is correct.

Thanks! So, it's a kind of March brown (http://flyfishingentomology.com/WAMayflyDescription.php?Fa=Heptageniidae&Ge=Rhithrogena) right? I will ask there too.
Hopefully @Taxon and/or @Mark Melton will see this post and be able to supply an informed answer. Those guys are great! To me they all look alike.
Heck, I don't know what to call it. Usually this time of year on the Snoqualmie forks, I thought the mayflies I typically encountered were Red Quills. I hardly ever saw the duns, though, usually it was the spinners. All three of those bugs you have pictured have different colored bodies and wings, too. You may have more than one species. Like Tom mentions, ask the folks who know: https://pnwflyfishing.com/forum/index.php?forums/fly-tying-and-entomology.8/

If those guys were here, they would say "we need a better picture". As an amateur, I would say the first two are March browns (which are Rhithrogena, btw), a staple mayfly in freestone streams, but the bottom one is a different species whose name eludes me at the moment. Will get back to you if it comes to me.
The pale evening dun is a possibility as well, the head indicates a clinger type of mayfly at any rate, as well as the hindwings.
Hope this helps.

You guys have probably got it right at Rhithrogena, with the first and third being imagos (spinners) and the center one being a subimago (dun). The caddisfly looks like a Dicosmoecus species, possibly D. gilvipes.
