#1 is a variety of Happ Ultimate
#2 is a Happ Competition
#3 is a Wico 8-way.
The dustwasher is likely from a Wico that shipped with a P360 kit on it, but I don't know for sure, I've never seen a washer like that before.
I don't have a Wico assembly diagram, but the handle goes in from the top- you'll have to wiggle and shake things around to get it through the metal washer that's floating around inside the base. Then the small spring (about a half inch tall and just big enough around to fit on the handle shaft) goes on from the bottom. Then the actuator (dust & rust covered white plastic cylinder, about 3/4 inches long) goes on, with the small end facing up into the joystick base. Last, the e-clip (flat metal disc open on one side) slips into the slot on the bottom of the handle.
