Till oracle 7.0 only 12 triggers could be associated with a given table, but in higher versions of Oracle there is no such limitation.

You can create n number of triggers, try the below trigger on a same table by giving different names with different when conditions.

Code
  1.  

  2. CREATE OR REPLACE TRIGGER trg_test_null_8

  3. before INSERT ON test_null

  4. FOR each ROW

  5. WHEN (NEW.a = 8)

  6.  


  7.   NULL;

There is no limit to the no. of triggers that can be created on a table. Whereas there are 12 possible combinations of triggers that can be created using the combination of (insert/update/delete)*(Before/After)*(Row Level/Statement level)

There is no technical limit on the number of triggers you define (or, at least, not one that any rational person has ever hit). It generally wouldnt make sense to have more than one trigger of a given type on a particular table though you can come up with situations where you might want to have multiple triggers of the same type on a single table.
