I kept this one due to the interesting behavior. Had to shoot straight up into the sun so I only ended up with one shot half-way decent. The large black spider is a Bold Jumping Spider and it's prey that lost the battle is a Furrow Orbweaver. They are about the same size. The small spider above them is probably the male furrow orbweaver, they are much smaller than the females.
Bold Jumper (Phidippus audax)
Furrow Orbweaver (Larinioides cornutus)
