I have three plants whose names I don't know. Can anyone help?
Image 1 looks like Lobelia.
Image 2 looks like a Medic of some variety (Medicago sp). Perhaps Medicago polymorpha

I must agree with #2 looking like a Medicago sp. Though I've not seen that particular bloom color, the plant looks identical to a Medicago sp. that I had ID'd not to long ago.
The leaf shape does not look right to me to be a Medicagon nor do the infloresences. I'm leaning toward Birdfoot Trefoil, Lotus corniculatus http://davesgarden.com/guides/pf/showimage/302261/
Edited to specify plant #2

Agree that #1 is likely a Lobelia, perhaps L. kalmii or L. nuttallii, two of the few that display flowers interspersed with narrow leaves. If one of those, most likely L. kalmii since it occurs near-by in Washington and Idaho.
I think you're right greenthumb99 - It may well be Birdfoot Trefoil. At first glance it looked like the burr medic we get in lawns here in Western Australia. :-)
The leaves of #2 do look like Medicago…But the flowers are totally different…I also think you may be right greenthumb.
