I would normally post this in the plant ID forum, however being the plants are only seedlings I thought this might be the best place to ask. The plant with the two longer looking leaves I believe to be Cosmos, the other plant could possibly be Cleome. I had both of these planted in this bed last year and now have hundreds of seedlings popping up. I don't want the weeds to get a head start so I would love to pull them if they are not actually flowers. Anyone familiar enough with seedlings to recognize them?
