1. Probably Helpis minitabunda a jumping spider. Other images show this species missing a leg or two, as well.
2. The smaller of the 3 was taken at night. I have not seen the spider during the day. It may be a species of flower spider or a juvenile wolf spider, perhaps?
3. A medium size grey hairy spider. Reminiscent of a Grey Huntsman, but the mandibles appear too long and the eyes do not have that binocular look, typical of hunting spiders. It was guarding a small web on the side of a galvanized shed.
