We have 7 Dlink DGS-3120 48 ports Gig switches stacking together and all ports are being used. Each switch represents a single segment of our working area. it is working well without any issue.
My question is that there is a 5-4-3 rule for network topology, but looks like our switch stack got nothing to do with this rule….? or newer technology has overcame the 5-4-3 limitation?
any idea why?
another question is how many switches can be connected in series?

The 5-4-3 rule is largely outdated: A switched Ethernet network should be exempt from the 5-4-3 rule because each switch has a buffer to temporarily store data and all nodes can access a switched Ethernet LAN simultaneously. More on the 5-4-3 rule here.
