Answer 1

You can join to the country_master table 10 times or create a function to return the name like:
select sales_date
       sales_value
       b.country_name lst_ctry1_name ,
       c.country_name lst_ctry2_name,
       d.country_name lst_ctry3_name,
       k.country_name lst_ctry10_name
  from country_master k,
       country_master d,
       country_master c,
       country_master b,
       sales_dtls a
where a.lst_ctry1 = b.country_code
   and a.lst_ctry2 = c.country_code
   and a.lst_ctry3 = d.country_code
   and a.lst_ctry10 = k.country_code
OR
create or replace function get_country_name(p_code varchar2) return varchar2 is
v_name varchar2(1000);
begin
select country_name
   into v_name
   from country_master
  where country_code = p_code;
return v_name;
end;
select sales_date
       sales_value
       get_country_name(lst_ctry1),
       get_country_name(lst_ctry2),
       get_country_name(lst_ctry3),
       get_country_name(lst_ctry10)
  from sales_dtls a
