Well, you've definitely got a strong Ha line there, but it appears to be slightly redshifted, as they all do (if they're all hydrogen lines, in fact). Since I don't have a calibrated reference spectra on me, it's hard to tell what the other lines are. However, you do have a couple of close lines...the one at 488.3nm is close to the Hb (hydrogen beta) line and the one at 436.6nm is close to the Hg (hydrogen gamma) line.
Just to help you out here....read this (luckily it jogged my memory when I read the equations...simple stuff, really)...
Hydrogen Balmer Series
If they're indeed redshifted Hydrogen lines, then it's because of the motions within the Homonculus itself. Most likely from the lobe moving away from us. Or at least from gases (including the lobe) that are in motion away from us.
