What is the Difference Between Public & Private IP?

Do you have tutorial on how to set up multiple access points
Example property A has Fibre To The Home ONT and router while property B and C re don't have internet access if we exclude WiFi signal from property A
So how can one share property A FTTH with property B and C
I have seen media convertor mentioned in other tutorials but I need clean to understand video let's say I can terminated LC to LC APC cables which I plan to connect to property A ONT and router and am willing to use two more routers (1 at property B other one at property C) connected via media convertor {Fibre patched cables and ethernet cables}
How to configure internet speed per access point maybe I have 75mbps DL by 40mbps UL
I want property A to have 30mbps DL by 15mbps UL
Property B to have 35mbps DL by 15mbps UL
Property C to have 10mbps DL by 10mbps UL
Please do video about this including information regarding how to set up IP addresses for this set up and WiFi set up for all 3 routers
