/storage/emulated/0/: to my knowledge, this refers to the "emulated MMC" ("owner part"). Usually this is the internal one. The "0" stands for the user here, "0" is the first user aka device-owner. If you create additional users, this number will increment for each.

/storage/emulated/legacy/ as before, but pointing to the part of the currently working user (for the owner, this would be a symlink to

/storage/emulated/0/). So this path should bring every user to his "part".

/sdcard/: According to a comment by Shywim, this is a symlink to...

/mnt/sdcard (Android < 4.0)

/storage/sdcard0 (Android 4.0+)
