I can't remember, but has hiccup ever been jealous? Like, I remember him gloatting when he was beating snotlout in thawfest but I can't place him ever being jealous over someone or something. Can you?
Since you specifically pointed out Thawfest, I think there is a touch of jealousy there, but not during the beating Snotlout parts, the parts prior to that. He was a envious that Snotlout won every year. Jealousy over that definitely was a motivator for his behavior in some of that episode.
Plus, arguably some jealousy was likely a motivating factor over his behavior in HTTYD1. He wanted the status that killing a dragon would give him. That’s what he wanted. I would argue that is jealousy.
I mean isn’t wanting to be something you’re not (to use Gobber’s words earlier in the film), a very basic form of jealousy?
Plus... there was definite jealousy happening in HTTYD3 with how he felt about the Light Fury and Toothless. I think he is like “I don’t trust her!” or something at some point. Yeaaah, our boy is jealous.
So, yes, Hiccup does experience jealousy. I think it’s couched in a way that doesn’t come off as jealousy, though.
