First of all, Lumia phones (aka the WP8 OS) is one of the best in security when compared to its counterparts. Secondly why would you hand over your phone to someone (in this case your friends) whom you do not trust? If you want only some public apps (Music player, Camera, etc) to be accessible without unlocking the phone, you could always activate Kids Corner and place the app shortcuts in there. There are certain 3rd party apps which provide additional security with pin-code for your Images/Videos, you should check them out.
