Several sources say that all have been released except for the director of the video (not the art director of the video, who is mentioned above).

Iran authorities arrested the three men and three women who took part in the amateur YouTube video of "Happy," which was recorded in an apartment and on a building rooftop in Tehran, Iran. The women can be seen without hijabs; not wearing the head covering is illegal in the country.Their arrest, just like the original video, spread quickly worldwide, sparking a Twitter campaign with the hashtag #FreeHappyIranians. Even Pharrell joined the chorus, condemning the arrest on social media.
