Answer 1

Assuming you mean as an output parameter of pl/sql procedure being called from pl/sql...
declare
  type refcur_type is ref cursor;
  type tab_user_tables_type is table of user_tables%rowtype index by binary_integer;
  refcur_user_tables refcur_type;
  tab_user_tables tab_user_tables_type;
  row_user_tables user_tables%rowtype;
  procedure get (
    out_refcur_user_tables out refcur_type,
    out_tab_user_tables out tab_user_tables_type) is
  begin
    for row_user_tables in (select * from user_tables) loop
      out_tab_user_tables(nvl(out_tab_user_tables.count, 0) + 1) := row_user_tables;
    end loop;
    open out_refcur_user_tables for select * from user_tables;
  end get;
begin
  get(refcur_user_tables, tab_user_tables);
  dbms_output.put_line('from table ...');
  for i in 1 .. tab_user_tables.count loop
    dbms_output.put_line(tab_user_tables(i).table_name);
  end loop;
  dbms_output.put_line('from reference cursor ...');
  loop
    fetch refcur_user_tables into row_user_tables;
    exit when refcur_user_tables%notfound;
    dbms_output.put_line(row_user_tables.table_name);
  end loop;
end;
