In your first pic, the axle looks like is isn't in the whole way, that will create a leak there.
2nd pic, could be a leaking valve cover gasket, head gasket, or the fitting where the oil pressure switch piping connects to the block.
5th pic, could be leaking distributer o-ring, intake manifold gasket, or valve cover gasket. I'd look at the base of the distributer where it enters the block, that O-rings is famous for rotting out and leaking.
The rest of the pics, might be a leaky base pan gasket, but you can see the oil is running from higher up.
The oil and trans fluid over the muffler and bottom of the trunk is just a result of the oil being blown back under the car while driving along.
I'd start with the distributer o-ring, and checking the valve cover gaskets throughly, those are the 2 most commin places to leak.
