Assassin Bug
The three pictures seem to be of different bugs, perhaps different stages?
I believe that the one with the red markings is a wheel bug nymph.
In two of the pictures you can see the beak.
Great pictures by the way.

Wheel bug nymph
Two of the three are wheel bugs. The newly-hatched nymphs of the wheel bug have a bright red abdomen they hold upright. As they age, the red color fades and they get the "gray hair." The crest apparently does not appear until adulthood.
