dang i didn't know bumping was a no no :(
Ken: I just downloaded it yesterday but haven't had a chance to use it yet...I took a bunch of pictures of wildflowers on a Fallbrook cleared Chapparrel hillside and wanted to see if they could ID them, but then I synced my phone and the pics aren't on...
whether it's hensbit, as I suggested, or gill over ground, as Laramill suggested, i'm sure the tortoisetable will have something similar to say about them: they're closely related and wikipedia lists both as edible to humans
That first one looks a lot like some of the weeds my grandmother had in her garden when I was a kid...and she lived in the pacific northwest as well...it looks to be close to putting up a flower, if you can get a clear picture of the flower once it blooms, I might be able to tell if it's a type...
It's still hard to tell from the pictures as they seem a little out of focus, but I'd tentatively go w/Yvonne's ID of Tradescantia...maybe Tradescantia ohiensis? the close up of the flower seems to have only 2 petals rather than the 3 typical of the species, but maybe it's an anomaly or the...
based on your two suggestions, I would go w/the latter: it doesn't quite look like bittercress, especially in the flower, so I don't think that's it.
that said: this doesn't grow in Southern California, so I've never seen it...but from google image search, I think Cochlearia genus might be a...
those little white flowers look as though they are from some sort of bulb or tuber: in general, bulbs such as allium, daffodil, hyacinth, lillium are not supposed to be fed.
the first 3 pictures you posted do look like some type of lactuca or prickly lettuce, but the one w/the heavily serrated...
not a problem, jbms, I just saw a picture in the first post that was obviously not of your weed and wondered how posting it could possibly help you in your situation. The second photo looks more like a spurge than purselane: i believe that's a 'feed in moderation', although I seem to recall some...
it looks like your picture is from here: http://www.delange.org/DaleaParry/DaleaParry.htm
if so, it's not very helpful to submit a picture that isn't actually of the plant you are trying to ID...at best you will just find someone confirming that the website is correct in their ID of what they...
well...the first one does kind of look like some kind of carrot, but you should check queen anne's lace and other wild carrots against water hemlock first (as Hemlock is poisonous whereas those others are not)

your second photo set is of common mallow: edible.
