I think plant 21 is some variety of persicaria (knot weed).
I think plant 22 is probably thread-leaf coreopsis - variety names are
zagreb and moonbeam. I'm not sure about plant 23 - at first I was thinking
euphorbia snow on the mountain, but in the closeup it looks like fuzzy
flowers of some sort, not bracts.
