Package should contain
1. create table -
2. insert into the above table the results of the primary query
3. update the table created from number of sub queries.
The primary query will have the mandatory information which all staff should have ex
1. Staff ID – Primary key, 2. Last name, 3. First Name, 4 Position, 5. Department
Sub queries :–
Subquery A- retrieve private address
The results from the Subquery A should update the table–against the Primary key
Staff ID, Postal Address, Person ID, Address Line 1, Address line 2, City, State, Country
Subquery - B
Insert into the table above
Subquery C
Insert into the table above

Insert into the table aboveVery strange requirements. First of all you shouldn't create Table from PL/SQL. Creating tables is DDL and should be done once. Not at runtime.
Where you say subquery, you mean Functions? Function which returns data based on the input parameters. Or Procedures which INSERT data into the -already existing- table.
You may want things like:
function fget (p_param in varchar2)
return sys_refcursor
is
   retval sys_refcursor;
begin
  open retval for select * from table where col = p_param;
  return retval;
end;
procedure ins (p_param in varchar2)
is
begin
   insert into table
   (col)
   values (p_param);
end;
