Here's some info for you (in reverse order!):
Goosegrass/Cleavers/Sticky Willie. Galium aparine - L.

I also gather the very young tips for salads. They have sharp edged stems and leaves and older shoots feel very strange on the tongue (ouch) when raw so always pick young for this.
Wood Sorrel (common) Oxalis acetosella white or pale pink flowered
Wood Sorrel (Yellow) Oxalis stricta
http://www.pfaf.org/database/plants.php?Oxalis+stricta
All the wood sorrels have the shamrock leaf and taste tart & sharp like lemons. Use raw in moderation or cooked (which is supposed to destroy the oxalic acid).
Wood Sorrel Sauce
This is based on chimichurri, a classic Argentinian herb sauce. Serve it with grilled meat, poultry or seafood; use it as a marinade; or add a few spoonsful to potato salad or bean dishes. Serve with Grilled Venison Steaks, below.
1 jalapeno pepper, stem removed
4 to 6 cloves garlic
2 bay leaves, broken up
1 teaspoon fresh marjoram leaves
2/3 cup (tightly packed) wood sorrel leaves
2/3 cup (tightly packed) parsley leaves
1/4 cup white wine vinegar
2 tablespoons extra-virgin olive oil
1/2 teaspoon salt, or to taste
Remove seeds and veins from jalapeno if you prefer a less spicy sauce. In food processor, combine jalapeno, garlic, bay leaves and marjoram. Pulse until finely chopped. Add wood sorrel and parsley; pulse until finely chopped. Add vinegar, oil and salt; pulse until well blended. Add salt to taste. Serve at room temperature; refrigerate leftovers for up to 5 days. (About 2/3 cup sauce.)
Dock (Broad-leaved) Rumex obtusifolius L.

I find these bitter raw, although some sources suggest blanching them. I have sucessfully used them as cooked greens though. You can also harvest the seed and use it like a grain. IRRC it was one of the seeds found in the stomach of the Tollund man bog body.
Prickly Sow Thistle Sonchus asper L.

There are various types of sow thistle & it's a bit hard to tell what yours is. Smooth sow thistle is supposed to be vitamin rich. Prickly sow thistle needs the spines removing before use (obviously!). I have tried neither yet. Let me know how you get on! Look for the countrylovers website which has loads of recipes and ideas, it's very good.
Dove's Foot Cranesbill Geranium molle

I'm unsure about the edibility of this one, but it does have some medicinal applications.
Use the names both common and latin for searches and you might be surprised at what you find. Hope that helps!
