From my experience with men, even the shy ones, they always let me know when they were interested. Men are not that complicated as we women like to believe. When a man is interested, he'll let you know, simple as that. Unless of course he's already involved with someone else.
Since you're curious and you are friendly with him, why not just ask him?
Things rarely stay at the same level (i.e. 5 to 8 emails a day), there will be fluctuations - but it seems like there hasn't been an actual date, you've gotten to hanging out with friends stage.
perhaps there's a movie you might talk up and if he's into it too suggest seeing together...
