Now I know that these are weeds, and I have even have half-way identified a couple but this last one is stumping me. I know that the vast well of knowledge of you guys will not fail.

And this one I noticed in this plant pot. I was hoping it was some kind of tree so I could transplant it.

The first one is some variety of ivy...(hedera...)
2nd one almost looks like a Heuchera.

First one, to me, looks like Cocculus carolinus ("coralbead," "snailseed")... [HYPERLINK@plants.usda.gov]

Second does look like "ground ivy" (Glechoma hederacea) to me... [HYPERLINK@plants.usda.gov]

Third looks like an elm seedling.

(edited to add quotation marks around Glechoma's "vernacular name" to avoid confusion with true ivy - Hedera)

#1 is probably Common Ivy Hedera helix, but the pic isn't clear enough to be 100% certain.

All right!!! I knew I could count on you. Now one more question about the first one. Is it poisonous or an irritant?

Not normally, though some people can be allergic to ivy sap and get a rash similar to mild poison-ivy burns.

Hedera Helix Ivy is a Far Distant cousin of poison ivy, and not a 'recognized' irritant the way Poison Ivy is.
It's a common houseplant here, and I have some Hedera Helix in my flowergarden that I started as a houseplant. It is a perennial, though.

Snailseed, if berries are ingested in quantity, might cause an upset stomach and/or nausea. However, many homeopathic remedies exist from this plant (ref. Google search for "Cocculus allergy").

Oh, did I mention I think the first photo is snailseed and not ivy?

Any chance of a clearer, higher resolution pic of #1?

I agree...it still looks like common ivy to me...but I've never seen snailseed, so.......

not snailseed:
Got this from [HYPERLINK@www.plantoftheweek.org]
"Cocculus carolinus, or Carolina Snailseed, is a deciduous vine native to Oklahoma and most of the SE United States. Leaves are dark green and typically heart-shaped to 4 inches long and 4 inches wide, with sometimes significant variation in leaf shape. The vine itself will reach about 12 feet with a 4- to 6-foot spread. I believe it is under utilized in landscapes in Oklahoma. They are hardy from USDA zone 5-9.
Blooming Time: Spring. The flowers are very small and inconspicuous. These mature into showy fruits in late summer-fall, forming bright red ¼ inch berries.
Culture: Cocculus carolinus need partial shade and moderately wet soil conditions. When grown in the greenhouse, we use a soil mix consisting of 2 parts peat moss to 2 parts loam to 1 part sand or perlite. The plant should be kept moist at all times during the growing season. Fertilize monthly with a balanced fertilizer. It does get quite large in pots, so some trimming is needed to keep it within bounds. Pruning should be done in late winter or early spring before new growth begins.

Propagation: Cocculus carolinus is propagated by cutting of half-ripened wood or by seed. The seed needs cold stratification of 3 months. Seeds germinate in 21-30 days at 68° F. "

Here's a pic of snailseed - note the leaves:

Would it be correct to state that an identifying feature of Hedera helix is its mature foliage has veins at least slightly but noticeably lighter in colour than the rest of the leaf?

Often true; whether always, I'd not like to say. Tipping down with rain just now so I don't want to go out to check any just now!!

Another piece of evidence to support my supposition:

[HYPERLINK@www.sbs.utexas.edu]
Please refer to the photo with the caption: "leaf--in many cases Cocculus carolinus is easily recognized because its leaves look like an elephant's head..."

Please compare the leaf farthest to the right in GeorgetheFarmer's photo with the one mentioned above.

Any closer to being solved?
