I think it’s far too early for Regina to get her second chance at love with Robin Hood, since they haven’t even met yet. So, I don’t think Robin Hood and Roland would become Henry’s new step-father and step-brother until close to the end of S4, at the earliest. Also, I doubt that Emma would officially get engaged to anyone, Hook or Neal, by the end of S3. Emma getting her happy ending is almost certainly an end-of-series type of thing. So, even if Emma chooses a man by the end of S3, I highly doubt anything official would come of it.
