Assuming all 5 are using the same number of HTTP connections, then yes.

No. If you use a class 2 delay pool and set 3 KB as the individual limit,
then they will never be able to use more than 3 KB, even when bandwidth is
available.

The closest you can get is to set the aggregate limit of a class 2 delay
pool to (3 KB * [number of users]), then set the individual limit to -1/-1.
However, this is essentially equivalent to using a class 1 delay pool with
the same aggregate limit as the class 2 delay pool.

The only benefit to using a class 2 in this way is that users with an
excessive number of concurrent active HTTP connections (such as a broken
download manager or a badly tweaked browser) will not get an unfair share
of the aggregate limit. This can occur in class 1 delay pools if you do not
limit the number of connections per IP address.
