The top one is rhubarb chard. Chard comes in 2 varieties, white and red. The white is Swiss chard, the red is rhubarb chard - not to be confused with real rhubarb. Rhubarb leaves are mildly toxic to some people, while both red and white chard are very edible, both stems and leaves. If in doubt, bite the red stem. Chard is fairly sweet like lettuce, etc. Rhubarb will be quite sour.
As said before, the bottom pic is cabbage. The heads haven't developed yet so it's all leaves. The plants at the bottom of the top pic are turnips.
