#3 looks like threadleaf phacelia. (It also looks a bit like blue flax, but I took a picture of threadleaf phacelia on Dog Mountain on 5/17 of last year, and I think that's what you've got there.)
#4 looks to be in the same family as cryptantha; maybe rusty popcorn flower?
Yes, #5 is forktooth ookow, possibly the best name ever for a wildflower...
#13: It's growing like a coralroot (which is an orchid), but the buds are too round... I think it's in the Ericaceae (heath) family. My best guess would be a leafless (saprophytic) subspecies/phase of some kind of
Pyrola.
#15 looks exactly like the picture in my book of big-leaf sandwort.
#17 is too small to identify, but it reminds me of baneberry.
#19 is probably ballhead waterleaf, although you don't usually see it that blue.
#21 is definitely a violet. Maybe hooked violets.
The background of #22 is strawberries, but obviously not the foreground! The small white/pink things look like they might be related to either phlox or fireweed; did they have 5 or 4 petals?
