trafshow from ports.

Is systat able to show kb/s realtime?

There are quite a number of options available, depending on whether you're 
mainly 
interested in a 'live' view or collecting data over time.

For live views I see you've got several answers already, and of course
systat offers several views that may fit the bill.

You could also instrument your rule set with labels and use pfctl to extract
data, or you could even use pflow(4) and the netflow collector of your choice.

I've written a few related articles, but the one that has possibly the more
useful info is this one: 
http://bsdly.blogspot.no/2014/02/yes-you-too-can-be-evil-network.html

Also, Michael Lucas' book (referenced in the article) is worth buying and 
digesting if you're at all interested in the subject (this is true about most 
of Michael's books, btw)

Re: Packets/Bandwidth Monitoring

I wrote a stats script for PF that can show bandwidth per label.

If you can identify your user with rules that match a label it would work.

lots...depends what you're looking for. some options:

different PF rules per user, parse the counters (mrtg with custom
monitor, homemade software, something else)

use a managed switch and monitor the stats (mrtg, rtg, others)

use a seperate nic for each user and monitor the stats (netsnmp and 
same software as above)

pcap-based software like http://www.qosient.com/argus/, darkstat,
ntop (as you found), softflowd (and a netflow collector)

pfsync-based software (pfflowd and a netflow collector)

I use cacti.  I've never set it up to monitor traffic for a particular
user, but it uses snmp so you could just use cacti to monitor some
custom rule or something.
