Translation of "Hee" in Japanese

"Hee hee," his mother chuckled, shaking her head.

「うへへ」おっかさんは首を振りながらクスクス笑った。

That looks like the kind of guy who'd buy me lots of designer goods tee-hee-hee.

ウフフ。あの人ならたくさんブランド品買ってくれそうだわ。

I carried the heavy bags back from the store chanting yo-hee-ho all the way home.

店から家まで、重い荷物をエッサッサと運んだ。
