Is it possible to get user's ethereum wallets name from the address he is using?
Your question is still not clear. No, you can't know the name of the person by seeing his/her address. But the addresses can be tagged on popular block explorer by you or the wallet owner so that you would easily recognize who the wallet belongs to. Popular wallet from exchanges are officially tagged by the exchange reaching out to the block explorer.
yes, it's clear that just looking at the address doesn't tell us who owns the wallet. for example when we get a token distribution from a project, we don't know who sent it. but if it is the token from the bounty that we are participating in, then the team will send it to us.
