the first one looks like a kind of poke weed. If it is Poke, the berries make a good die and the leaves can be blanched and eaten.
I cant see the second plant very well
Diversified Food forest maker . Fill every niche and you'll have less weeds (the weeds are the crop too). Fruit, greens, wild harvest, and nuts as staple. Food processing and preservation are key to self self-sufficiency. Never eat a plant without posetive identification and/or consulting an expert.
Yeah, for sure poke on the first one, it is delicious and some old timers I know say they wouldn't change the water on first poke shoots any more than for asparagus. Later grown leaves as a famine food, maybe. Poke is IMHO the most delicious greens, simply prepared in soft water with country ham or salt pork and seasoned with hot pepper vinegar...
