Answer 1

Facebook

Without login you can fetch the limited information using the username. Since for the rest you have to ask permission from the user and for that you have to implement the facebook login.

You can use the Graph API to get the info-

http://graph.facebook.com/username

To get the profile picture-

http://graph.facebook.com/username/picture

Youtube

You can use the Youtube API

Similarly you can search for the other APIs..
