- Is my internet services provider able to see the websites I visited
No. Your Internet service provider can not see which website you visit (I suppose you use Tor correctly without your personal settings/configurations you may have done. Tor will take care of your DNS leaks and so on)
- Is it possible to retrieve a login information like username and password of my email account from intermediate node between Tor
browser and web server
First of all, using your credentials to log into this or that website breaks, by time, the anonymity Tor provides you. Also, an attacker may eavesdrop the exit nodes where Tor does not control the traffic.
- Is it possible to retrieve email content like mail body and attachments from intermediate node
Once again, using your credentials through Tor breaks your anonymity. Tor intermediate nodes are too hard theoretically to break (of course, there are buts). Real life eavesdropping that targeted Tor users has been done on exit nodes such as when this Swedish researcher compromised username/passwords of lot of Tor users (in which case, of course, your attachments and so on are also compromised)
