Supply and demand.
Commercial rent has gone down in HK, because as you point out, there are lots of empty shops and offices.
Rent in many residential areas has not, because there is a shortage of appropriate residential accommodation in HK, that a fall of 5% in population doesn't really dent. Rent in some residential areas that have seen more of an exodus, has fallen.
would these companies move to other jurisdictions if Hong Kong's profit tax goes up?

Interesting. I thought this is the case:
Generally speaking, a company is liable to profits tax if it carries on a trade, profession or business in Hong Kong and has profits arising in or derived from Hong Kong from such trade, profession or business. This applies equally to Hong Kong companies and those incorporated overseas.

It is the case, and the vast majority of the companies you listed carry out a zero to minimal proportion of their business in Hong Kong.

I was thinking of the largest 10 employers in HK (ie running business in HK). I don't know why the list is not showing:
