Answer 1

Your insert all syntax is malformed, you need multiple into ... values ... pairs. At the moment it's trying to interpret 100 as a column name, hence the specific error you're seeing.
You also have hire_date(...) instead of to_date(...), and you're missing one of the comm values; assuming that is supposed to be null:
INSERT ALL
INTO emp (empno, empname, mgr, hiredate, sal, comm)
VALUES (100, 'MARK', 'CXS', TO_DATE('1999-09-08', 'yyyy-mm-dd'), 8000, 'axw')
INTO emp (empno, empname, mgr, hiredate, sal, comm)
VALUES (200, 'peter', NULL, TO_DATE('1996-01-08', 'yyyy-mm-dd'), 9000, null)
INTO emp (empno, empname, mgr, hiredate, sal, comm)
VALUES (300, 'karl', NULL, TO_DATE('1995-05-08', 'yyyy-mm-dd'), 5000, 'AZQ')
INTO emp (empno, empname, mgr, hiredate, sal, comm)
VALUES (400, 'MAx', NULL, TO_DATE('1994-04-08', 'yyyy-mm-dd'), 10000, 'DES')
INTO emp (empno, empname, mgr, hiredate, sal, comm)
VALUES (500, 'Maggie', 'SAQ', TO_DATE('1998-06-08', 'yyyy-mm-dd'), 20000, 'QAS')
SELECT * FROM dual ;
5 rows inserted.
I've also changed the stirng literals 'NULL' to plain nulls, as it seems much more liekly that is what you really intended.
And I've changed the date format masks to use - rather than /, to match the values. But if you're using fixed values like that it's simpler to use date literals instead, e.g. instead of
INTO emp (empno, empname, mgr, hiredate, sal, comm)
VALUES (100, 'MARK', 'CXS', TO_DATE('1999-09-08', 'yyyy-mm-dd'), 8000, 'axw')
use:
INTO emp (empno, empname, mgr, hiredate, sal, comm)
VALUES (100, 'MARK', 'CXS', DATE '1999-09-08', 8000, 'axw')

Answer 2

The syntax for the INSERT ALL statement in Oracle/PLSQL is:
INSERT ALL
INTO mytable (column1, column2, column_n) VALUES (expr1, expr2, expr_n)
INTO mytable (column1, column2, column_n) VALUES (expr1, expr2, expr_n)
INTO mytable (column1, column2, column_n) VALUES (expr1, expr2, expr_n)
SELECT * FROM dual;
So in your case you can use
INSERT ALL
INTO emp (empno, empname, mgr, hiredate, sal, comm)
VALUES (100, 'MARK', 'CXS', TO_DATE('1999-09-08', 'yyyy-mm-dd'), 8000, 'axw')
INTO emp (empno, empname, mgr, hiredate, sal, comm)
VALUES (200, 'peter', NULL, TO_DATE('1996-01-08', 'yyyy-mm-dd'), 9000, null)
INTO emp (empno, empname, mgr, hiredate, sal, comm)
VALUES (300, 'karl', NULL, TO_DATE('1995-05-08', 'yyyy-mm-dd'), 5000, 'AZQ')
INTO emp (empno, empname, mgr, hiredate, sal, comm)
VALUES (400, 'MAx', NULL, TO_DATE('1994-04-08', 'yyyy-mm-dd'), 10000, 'DES')
INTO emp (empno, empname, mgr, hiredate, sal, comm)
VALUES (500, 'Maggie', 'SAQ', TO_DATE('1998-06-08', 'yyyy-mm-dd'), 20000, 'QAS')
SELECT * FROM dual ;
Also for any column you want blank/no value just put NULL if you include this as 'NULL' it will be considered as text NULL.
