I think at least one of them is kale?
The top plant resembles some pictures I was able to find of Lacinato Kale, which lacks the curly leaf edges of the more familiar Curly Kale varieties.
The lower plants are almost certainly some manner of Brassica oleracea but that is an impressively wide species. Because of it's youth it could be cauliflower, broccoli, cabbage, brussel sprouts or almost any other cultivar within the species. Time will tell what that plant is.
