The first two photos are of large non-web building spiders. These are hunters not trappers and while the first one is not much to worry about even though four inches across, the second one is not something you would really want to nip you. In the photo is it eating a camel cricket.
This leaf-footed (or leaf-legged or leaf-kneed or flag-footed, etc.) bug looks to be in the genus Leptoglossus. It is another true bug.
