The following answer is written as if we limit the scope of your question to "Does the following examples in learning Hong Kong's economy and socio-economic structures exist?"
(c) paying a visit to the HK Monetary Authority to learn more about economic growth, credit growth and monetary policy
The Hong Kong Monetary Authority (the de facto central bank of Hong Kong) has an information centre, which is "operated as a resource for HKMA staff members and as an educational and research facility for the public." Guided tours are available on a daily basis:
Guided Tours for the General Public
Guided tours (duration 30 minutes) for general visitors are available on
Monday to Friday 2:30 p.m.
Saturday 10:30 a.m.
(a) a tour through different neighborhoods with someone who knows about real estate and can talk about house prices, mortgages, buy-to-let business models etc.
This is difficult to achieve in full within a few days as the real estate situation in Hong Kong is extremely diverse, a reflection of the high economic inequality. The readily available exhibitions / guided tours include:
- The Hong Kong Housing Authority Exhibition Centre, which showcases the public housing development in the past 65 years.
- The Hong Kong Housing Society Exhibition Centre, which showcases the non-governmental rental housing development in the past 70 years. Guided tours available. (Choose the "EN" button on to top navigation bar for the English page.)
- The Urban Renewal Exhibition Centre "[provide] students, community organisations and the general public with information about the urban renewal in Hong Kong, including the problem of urban decay and the mission and work of the Urban Renewal Authority". Guided tour available on appointment. (The "EN" button is hidden inside the left navigation menu, accessible via the hamburger button.)
- The City Gallery, while tangentially related, "showcases the vision for the city’s planning projects but also act as a platform on which to engage and inform the public about our exciting and sustainable urban future."
Note these exhibitions and guided tours only represent a narrow perspective of Hong Kong's housing market. You might want to get in touch with some non-governmental organisations (NGOs) / campaign group for another perspective (googling "Hong Kong housing ngo" should get you started).
(b) tours through production or logistics facilities of companies doing business in HK
This is perhaps the most difficult one, as companies are more likely to be busy trading then entertaining visitors.
On the other hand, different groups including schools, learned societies and chambers of commerce do organise tours to such facilities, and the latter sometimes admit non-members to tag along. So such tours do exist, though just extremely difficult to find and plan in advance to fit into an overseas visitor's itinerary.
