I think it's really better to describe it than to spell it, but it's up to you. As for my two cents..
"Argh" is more frustration than a scream.
"Aaie" is someone with a squeaky voice. Mostly a child or a woman.
"Aww" would be either used for pity "Aww, there there", or a reaction to something cute. "Aww, look at those two"
"Aaah" would be a scream of surprise or fear
