#1 is definitely lamb's quarters.

#3 looks like redroot pigweed to me.

#4 could well be a sow thistle. There are at least three species and yours looks a bit different from the ones I see here, but I think that must be what it is.

Yay! Lambsquartes! I am going to transplant some to a bunny-weed bed. It is coming up everywhere.

I looked at the link for pigweed, and I think it matches. The first year it grew, I let a plant get very large because I thought it was from the spray millet I fed my birds. The flower head gets very long like that.

Thanks, maggie!
