You can add multiple Google Accounts and Microsoft Exchange ActiveSync accounts on your phone. Depending on the apps you download, you can also add other kinds of accounts, e.g. Facebook, LinkedIn, Skype, etc.
Some accounts can be added through the "Accounts" settings, whereas other accounts can be added using an app that works with those kinds of accounts. For example, you use the Email app to add IMAP and POP3 email accounts, and to add a Facebook account you'll need to download the Facebook app.
NOTE: To be able to add accounts on your phone and synchronize their data, you'll need access to the Internet using either a Wi-Fi or a mobile data connection. You may incur data connection charges when you connect to the Internet. Contact your service provider for more information.
