Answer 1

you cant kill your own session. Using alter system you(developer those who have alter system privilege) can kill other sessions.
eg:-
SQL> create user test identified by test;
User created.
SQL> grant connect,resource to test;
Grant succeeded.
SQL> GRANT ALTER SYSTEM TO TEST;
Grant succeeded.
SQL> grant select on v_$session to TEST;
Grant succeeded.
SQL> conn test/test;
Connected.
SQL> select sid,serial# from v$session where username='TEST';
       SID    SERIAL#
       521      37794
SQL> ALTER SYSTEM KILL SESSION '521,37794';
ALTER SYSTEM KILL SESSION '521,37794'
ERROR at line 1:
ORA-00027: cannot kill current sessionhad better, refer the link for more information.

KILL SESSION Clause
The KILL SESSION clause lets you mark a session as terminated, roll back ongoing transactions, release all session locks, and partially recover session resources. To use this clause, your instance must have the database open, and your session and the session to be terminated must be on the same instance. You must identify the session with both of the following values from the V$SESSION view:
•For integer1, specify the value of the SID column.
•For integer2, specify the value of the SERIAL# column.
If the session is performing some activity that must be completed, such as waiting for a reply from a remote database or rolling back a transaction, then Oracle Database waits for this activity to complete, marks the session as terminated, and then returns control to you. If the waiting lasts a minute, then Oracle Database marks the session to be terminated and returns control to you with a message that the session is marked to be terminated. The PMON background process then marks the session as terminated when the activity is complete.
Whether or not the session has an ongoing transaction, Oracle Database does not recover the entire session state until the session user issues a request to the session and receives a message that the session has been terminated.
