No, you cannot. What can you do inseatd is to create a new section in your Firebase database named imageNames and every time you add an image to Firebase Storage, add to coresponding image name under this new node like this:

Firebase-root
   |
   --- imageNames
           |
           --- imageId1: ImaneName1
           |
           --- imageId2: ImaneName2

To get all those names, just attach a listener on this imageNames node and get all those names from the dataSnapshot object like this:

DatabaseReference rootRef = FirebaseDatabase.getInstance().getReference();
DatabaseReference imageNamesRef = rootRef.child("imageNames");
ValueEventListener eventListener = new ValueEventListener() {
    @Override
    public void onDataChange(DataSnapshot dataSnapshot) {
        for(DataSnapshot ds : dataSnapshot.getChildren()) {
            String imageName = ds.getValue(String.class);
            Log.d("TAG", imageName);
        }
    }

    @Override
    public void onCancelled(DatabaseError databaseError) {}
};
imageNamesRef.addListenerForSingleValueEvent(eventListener);
