Uhh... I'm pretty sure each one is describing the same digit. So it'd be 0 (shape of the objects), 2 (number of legs, eyes and wings on the bird), 8 (number of legs, eyes and seasons in 2 years), 1 (unicorn horn, cyclops eye).
I mean, that's how I figure them to be. But I haven't found the third or fourth chest yet, so I haven't tested it yet.
