The rear main seal is leaking; the driver's axle seal is leaking; the transmission pan gasket is seeping; and the control arm bushing is torn and soaked with oil.
All rubber components soaked in oil and swelling must be replaced. The leaking fluid seals will require extensive work to be replaced and should be done by a qualified professional. I recommend having a certified mechanic, such as one from YourMechanic, to locate your leaks and perform the repairs needed to have this issue resolved.
