Given that all of them are all powered hubs so power won’t be the issue and you have enough space to put them. How much will it impact performance, latency or other things I don’t know about? Or it will straight up kill the port if there are too many hubs?
I don’t know about Daisy chaining them, but I found that the limit for usb3 is 16 devices. I was using 2 hubs and the integrated ports at the time.
According to some other answer here you could be able to have 32 devices but some devices register as two different devices, therefore you can only have 16
One port
To rule them all
