The 2nd and 3rd pics are Smartweed.

In the first pic on the left it looks like you have some Cardamine hirsuta that you will also want to pull before the remaining seeds pop. Euphorbia maculata or prostrata is present and should be pulled.

That might be a tiny Lamb's Ears tucked in the upper left of picture #3 (to the left of the smartweed).

If you can tell us what you sowed we might be able to spot some seedlings for you. At the moment the only thing I see which may not be a weed is the furry leaved plant (possible Stachys, Lychnis or Verbascum). I don't see any Cardamine hirsuta.

The vine could be a starving watermelon but they are outside my experience and there are various weedy vines with similar leaves, I believe.

The vine looks like a watermelon to me too.

You've had an id on that one. It's a Polygonum species aka Smartweed. A weed. Do some Googling and you'll see what we mean.

Thanks.. My husband a masters in biology just finally realized it was smart weed too!

So just the possible starving watermelon that I'll transplant! Thanks all for your help.

I think the fuzzy one is a first year Verbascum thapsus.

Yes - I tend to agree (see above)

Can smartweed be killed with sprays or is pulling the only way to try and keep it controlled??
