Weed Identification, Help!

There are a few different weeds out back. I need to know if they have any benificial value, and if not, the best way to erradicate these particular ones.

Here's another

And another:

These are the main 3 for now..
I would be so grateful with any
and all help/information about
these.

Here is one more..

number four looks like a member of the wild potato family to me... did it have small purple morning glory looking flowers? if so it is a good guy and keep it for the wildlife.

thanks mitch, i actually posted these in the wrong place... thanks for noticing it over here, my friend!

I reposted all of these in the ID forum and they jumped right on it. Your right that one is of the conv. family such as wild potato or mg..but it is a bindweed like plant. I haven't seen a flower on it.. The back yard is going to be for the wildlife and next Spring I hope to have it under way. I think that one can be contained well enough.. the rest of those are probably not desirable and will take some effort but once I can keep seeds from falling off them and get to the roots they will diminish.
Here is what our other friends had for ID>

Meanwhile, I have been rooting as much coleus as I can clip for y'all i..I brought them inside the bathroom window area it was too hot outside for them.. They are perking up well, the colors change on the one with maroon one depending on the amount of light they get, so that should be interresting too..I hope to have a lot by the 8th

No problem... there is no wrong place to post most things just some places that get better traffic.

Thanks Mitch!

That is a diffrent plant - one of the docks I think, the other is a vine that runs on the ground.
