Biggest clue is the P0139 code.
When an O2 sensor ages or gets old the signal from them slows down. When that signal slows to a certain point it triggers the code.
So all your codes except the PO446 are O2 sensor codes. they are for the O2 sensors in front of the Catalytic Converters.
I would change both of them out for new ones.
If you continue to run with faulty O2 sensors eventually you Catalytic converters will be destroyed.
PO446 there is an issue with the Evap shutoff valve. Make sure the wiring to it is good and replace the valve.
Can't help you with the HBA
