Answer 1

I would keep the type/object naming convention distinct from the table name.
In terms of assignment:
CREATE OR REPLACE TYPE to_emp AS OBJECT
(empid NUMBER,
age NUMBER,
dob date);
CREATE OR REPLACE TYPE tt_emp AS TABLE OF emp;
declare
v_emp tt_emp;
begin
select to_emp_obj(emp_id, age, dob)
bulk collect into v_emp
from emp;
end;
