What's your idea of the appropriate TCP window in this case (128 Kbit per
second)?

Understood.
So, in this case, when, for example, 20 users have their 400 (in total 8000)
 but whole bandwidth is 16000,
is there any ability to exceed their limits and give them all 16000?
But at the same time, if all 40 "allowed_hosts" use squid then no one takes
more than 400.
In other words, I try to divide all traffic equally between all connected
clients hosts dynamically. If 10 computers are switched on then the
bandwidth of each hosts is 16000 / 10 = 1600. But If 40 computers are
switched on then the bandwidth of each hosts is 16000 / 40 = 400.
Can squid-2.4.STABLE6 make it?
And if yes, could You write example of configuration.
