You can check under your applications "account preferences" or "account settings" and customize how and when your friends can view your online activity, if at all.

Let me just clarify. You don't want some FB friends to send you messages/email on Yahoo, or you only want yahoo friends to have full access? If it's the former, do not post your email address on the INFO page of your profile. If it's the latter, change your privacy settings - make a separate folder for your other friends (like gaming friends), go to privacy settings, then customize the corresponding setting. You can set information, photos and videos posted on your profile such that only a certain group of friends can either be given access or blocked.
