Suppose I'm using the write command to send messages to another host on the server. Can the root user or any other user get to know that we are interacting?

This can easily be done by any user that can capture packets on the interface (including root) and any intermediary devices. Moreover, root could in theory install additional mechanisms to hijack/inspect traffic.

You can always look into this

Is there any way that i can find the most frequently applications used by a user in Linux? In Windows you can read this information from registry.
Make sure that accounting is turned on:
chkconfig psacct on && /etc/init.d/psacct start
...and then get summary info with sa. Look at examples here or here.
My own experience is that the most frequent command in the account is a shell.

That's is the question.. how can i jail a user in a certain folder so that he can create files like images but can no go up using the command cd .. or see other folders outside?
Thanks.
Read about chroot http://linux.die.net/man/1/chroot
You can even create a minimal environment for the user
Alternatively just use file permissions so that the user is only able to see what the user should be able to.
