Jeez, just download
Every model stands on a different layer (as described in note on the right of the .blend file), to open level 1 press 1 key, to open level 2 press 2, and so on
select the model you want to export, open file (file -> open), then export to obj (file -> export -> Wavefront obj) ...
But no animations whatsoever in this way..
What program did you use to make models? Now I'm curious
