Three weeds growing in shade

This is growing in recently cleared heavy clay soil. It is in an area that stays on the moist side and is getting 4hours of direct sunlight (11am-3pm) per day. It resembles something like India Crabgrass but is obviously different. The sample I picked has still not dried and it’s been almost a week. I live in Zone 8a In South Carolina if it helps

 

Plant number two resembles some kind of Plantago major?

 

Plant number 3 grows in deep shade in among my hostas.

 

#1 - Dichanthelium oligosanthes or related

 

#2 Elephantopus

 

#3 might be an

Amaranthus.​

 

Amaranthus tends to have leaves with entire margin, this is more likely to be Acalypha rhomboidea.
