Was everything ok and then all these faults developed at once?

Seems odd that you would get so many together. I'd clear them (disconnect the Battery for 1 minute), go for a drive and then see which ones come back. They are mainly all related to the O2 sensors (suspect the upstream sensors are faulty and causing errors on the downstream ones), but error 19 is related to the throttle position sensor (but this could just be a spurious error, so clear errors first to see if it returns).

The car was going into limp mode 25 throttle disconnecting the Battery worked at first but Unfortunately disconnecting the Battery doesn't work anymore the codes are permanently there I'm going to buy two  upstream 02 sensors if that doesn't work then she will be sold 

Already replaced the throttle body with another used one

Just buy one to save money and see if that clears some of the faults before getting a second one. I'd recommend getting Denso brand ones, non-OEM sensors have been known to still trigger errors.

I am going to get one denso 02 sensor as you said cheers for replying
