Without more info on where these plants came from I can't id them all.* If any that I can't id are houseplants, it would be helpful to know and see the entire plant.*
For the ferns and the sprouts in your 8th picture, it would be helpful to know where in the US or other country these are located.
#1 & 2 - ??
#3 - fern.* If this was a houseplant it might be a Boston fern.
#4 - Another houseplant?* Either a gardenia (fragrant) or a camellia
#5 - fern
#6 - Primula hybrid aka primrose
#7 - I can't really tell as the photo is so close, but might be some type of daffodil
#8 - Caladium
#9 - ?? maybe sprouts from a tree or shrub?*
#10 - some type of Cedar, possibly Eastern white cedar.
When weeding, the best way to make sure you are removing a weed and not a valuable plant is to pull on it. If it comes out of the ground easily, it is a valuable plant.
