i apologize. i shouldn't have used simplified chinese characters; that only complicated the question. thank you for the answer.

[sora_Japan]

Don't apologize. so interesting.

[walgen]

do japanese always say 高 for expensive? do they ever use 贵? or 昂贵?

[sora_Japan]

Yes. We use '高い（たかい）'as 'expensive'.
And '背が高い' is 'tall'.

We use the '貴' as well. '貴い(とうとい)'. It is used a bit different.

This is '尊い（とうとい）' as well. It is used a bit different as well.

What do you read these? romaji please!
