Mexigonus morosus (female)

For your other spider, again I can't tell for certain from the angle the photo was taken, but Anasaitis canosa looks about right. Yours has the same white stripes on the sides of the cephalothorax and the white patches on the pedipalps that A. canosa has. If you can upload any more photos I might be able to confirm that ID with more certainty.

Yeah, it looks like that could be it. It might also be Naphrys pulex http://bugguide.net/node/view/38105 It's hard to see the markings on your spider's back from this photo, so I can't provide a 100% positive ID, only my best guess.

This jumper is not Phidippus audax. It looks like it is probably in the subfamily Euophryinae http://bugguide.net/node/view/35596/bgpage Here's a link to a photo of a female P. audax so you can compare it to your spider http://bugguide.net/node/view/318917
