Sorry, but you are going to need to do a better job on describing what you see and if it helps include a screenshot that does not include any personal information. For example, you simply said your "computer seen as Mac" without any context, so it is impossible to know where you are seeing this. Certainly there are many third party sites, including Google, that attempt to guess what device is accessing their service because Apple is not telling them, and they get it wrong. That does not mean that your account is compromised.
Another example is "iCloud 2 compromised by old emails yahoo Google and automation mirror g iPhone". What does that even mean? Without any details the only thing that is possible is to give you generic information for you to figure it out on your own and there is nothing specific we can provide.
