I've been thinking about using CoinJoin, with some of the addresses that I have in one blockchain.info wallet.

If I started a CoinJoin using all the UTXO of all the addresses, would they connect to each other before reaching the rest of the UTXO? Basically, I am trying to understand if someone could link all those addresses back to me (I am not talking about what info blockchain.info holds about me).

Would it look like those keys were held by the same person? If let's say I had 5 addresses and send funds to 8 addresses, would it be easy for someone to determine where those coins came from?

If the coinjoin transaction had several (many many many) other inputs and several outputs, then it would be difficult to trace which ones were yours. However, if you just used your own inputs and outputs, it would be fairly obvious.

Coin mixing is one of the good ways to do so.For your query about blockchain.info,they don't have any info about your wallet or the private keys.Only your email address where the unique URL identifier was sent.There is no professional way of determining if all those transactions or addresses belong to your wallet.Wallet.explorer is somewhat okay but I don't personally trust it because the new address and transactions are not reflected in there.Your address itself is anoynymous enough unless you have posted the ownership of your address somewhere.In that case,yes coin mixing is worth it.Try [banned mixer] .

Last time i used the shared coin-option in blockchain.info i did have to wait a long time because apparently, they're not adding a lot of fees to the transactions... Which is rather odd to me.
I ended up sharing inputs and outputs with about 20-30 other adressess, it was pretty good, the taint analysis didn't find anything substantial, neither did walletexplorer... I did read however that the process isn't perfect, but for me it's good enough.
