#1&2 do look like tomato plants, esp. if they have fuzzy 'pubescence' (if not ones you ate, most likely the cherry tomato 'weeds'), #1 looks small papaya as their leaf get more forked as they get bigger, but the picture is a little unclear, and #1&3 squash, looks a lot like the kabocha pumpkin I often get growing in my yard as an unplanted tasty accident
