Weed Identification...again...

Here are more weeds in my yard.

The first two appear to be vines, and the last one I believe is a baby tree of some sort?

 

First one might be a milkvine, Matelea, if it exudes a milky sap when you pull a leaf off.

 

Last one looks more like Ampelopsis arborea

 

No, the last one is much more "frilly" than what you suggested, unless this is just the younger version of that plant?

 

Well, number two exudes a milky white sap, but it looks completely different than the first plant. The first plant has very dark green leaves, and no milky substance when pulled apart.

I think it's a possibility that the second plant is Matelea though!

 

Yes, the second one is probably a milkvine. First one might be some type of Convolvulaceae.
