Chinese: 1. Is it considered bad luck for number 24? as it sounds like "starve-die-die"?

2. it was given 24$ in red envelope as to be the best man for my chinese cousin, is it even appropriate? (I'm kinda offended when I learned Chinese usually avoid numbers ending in 4 and I got just that)
3. She is from Chaozhou, does number 24 have any other meaning sounding?

Thanks.
