Ingus won't get Princess Sara. No one touches my Princess!! ORPHANS?? You impertinent fools... anyway, yeah, I guess Ingus will end up with her in the end. The NES version had (SPOILER)Sara wanting to remain with the main character of the party for a while longer, but I'm not sure about the DS version. I don't think Elia gets together with anyone because (SPOILER)she dies quite soon after you get her. Luneth and Refia could be a nice couple too.
