How much to bring to hong kong for a 5 days trip?

That really depends on what you are going to do there. It is actually very difficult to tell you how much to bring.

As a guide, the standard of living in Hong Kong is quite similar to Singapore. Do some budget planning and plan what you want to buy and how much for food. If you are going to Disneyland, you need to bring more too.

And if you really want to keep it very simple, just bring $100 a day. And if you are going Disneyland, perhaps bring an additonal $100 for each day in Disneyland.​​​
