I have Mikrotik v4.11 with hotspot user accounts. Can I limit the amount of download or upload(total download/upload not the tx/rx rate)?
You can only limit the number of bytes transferred on user accounts, not on user profiles.
Yes you can…

Excellent tutorial on bandwidth management… and user specific bandwith…
Queues only govern tx/rx rates, not total bytes transferred (which is I think what he was asking for).
