They only released Leonardo and Michaelangelo with this series - which were originally US TRU exclusives
Raphael and Donatello (as well as the other two) were released without comics, but with trading cards featuring original (or current, but Mirage style) artwork but with no other differences. These were general releases.
Raphael was also released as a 2014 black & white SDCC exclusive (with a stand, as standard for the SDCC releases. No other figures were released this way and Myer didn't get any of them in post SDCC (TRU had the black/green Leonardo from - I think - 2012 and Myer had the 2013 chrome-plated Shredder).
I hope that helps!
