How can i figure out the private keys from these information please?
If you just use the script or command that the OP did then you both will receive the same result.
Do you know exactly the password of your wallet.dat? then use the command that I posted above or this below
pywallet.py --dumpwallet --datadir=. --passphrase=YourPassword
Or if you don't know the password then you need BTCrecover tool the guide can find here
