Answer 1

As you commented, it looks as if you use Oracle.
In that case, schema name can't contain a "minus" sign (mahdi-jiradb) so that's probably underline (mahdi_jiradb) instead.
SQL> create user mahdi-jiradb identified by test;
create user mahdi-jiradb identified by test
*
ERROR at line 1:
ORA-00922: missing or invalid option
Unless, of course, you enclosed username into double quotes (but now you have to use it always, everywhere):
SQL> create user "mahdi-jiradb" identified by test;
User created.
Presuming that that's not the case, schema name is wrong. Check it.
Also, use one dot to separate schema name from table name.
Something like this might work:
INSERT INTO mahdi_jiradb.empier SELECT * FROM tamindb.users;
presuming that both tables share the same description. That's why it is better to explicitly name all columns involved, e.g.
INSERT INTO mahdi_jiradb.empier (user_id, user_name)
SELECT uid, uname FROM tamindb.users;
