Install SQL Server 2017 over 2016 Local DB and 2012 native client

I have downloaded Microsoft SQL Sever 2017 and would like to install it. But just to be sure I checked installed applications and I found that there is: - Microsoft SQL Server 2012 native client - Microsoft SQL Server 2016 LocalDB installed already. ( I noticed that because there was a Microsoft SQL Server folder in Program Files) Can I just proceed with the installation? I don't recall having installed SQL server previously so I am not sure why those two are installed in the first place Also, I would like to have SQL Server management studio installed. Is this a separated install?
