you are not "extracting" cash, you are claiming free giveaways that happened a long time ago. some of them are timed out since they are too old and some still work. if there was a fork that copied the whole blockchain of a cryptocurrency and created a new one and you had a balance prior to that copy/fork then you have the same coins in the forked chain.
you should beware of the risks of claiming these coins though, not just replay attacks but also infecting your computer by having to install shady wallets.
also take a look at this site: http://www.findmycoins.ninja/

Ill support the same statement of looking for team who gives out free coins from the beggining,yes you can make off money some fork coins on bitcoin but the process that you need to do will take you a long time and stress trying to log in or encrypt individual private keys.

Claiming forked coins and clams are literally the only ways to utilize addresses from the past which has no balance today. There literally are no other ways about it and even though you might claim some, chances are the value is not that high and the effort is somewhat futile, knowing that not all fork survived and not all of them held value over time. Best thing to do is to just look for other projects and do a fresh start rather than trying to dig your old addresses which, for the most part you already ended up forgetting.

If the wallet was empty then ofc you cannot extract any money from there because it was only given to people who actually we're involved in the market and kept some coins.

Secondly for the address which you claim might have some coins and are *yours *, you can just go and write the company or the wallet you are holding into , just write a really good email and ask them for help , about how you have forgotten and stuff, they will identify you again and possibly you will get back your wallet.

If you are talking about claiming the forked coins then you can either pay the professional to do they will take 10% and either you can check online there are number of steps given , but honestly it is not worth the time and effort because their value is well , a lot down even if you had like 0.1 of them it still accounts for 20$-30$ something and you would need your private key for that and that is risky.

If i get you right, you want to claim coins forked from bitcoin on empty bitcoin address that use to have bitcoin in it? Not possible as far as I can tell..
You can only claim forked coins if you have bitcoin in an address during forks

Nah, there's no other way than fork coins as mentioned, as long as you have your wallet loaded with bitcoin exactly with the timestamp of the occurence of the forks of bitcoin then you have it.
But other than that, don't expect that you can extract more cash with your empty bitcoin wallet.
