Answer 2

select T4.cnt +' '+T4.name from (         
select substring(name, 1, CHARINDEX(' ', name)) cnt,substring(name,CHARINDEX(' ', name)+1,LEN(name)) name from test4) T4      
left outer join (
select 1 as id,'Month' As name union all
select 2 as id,'Week' As name union all
select 3 as id,'Day' As name union all
select 4 as id,'Minutes' As name )T6
on t4.name=t6.name
order by t6.id,t4.cnt

You have to give all the distinct values (month,week etc..) in the order you want in the left table with "union all"

Answer 3

order by case when patindex('%Month', MyColumn) > 0
              then 0
              when patindex('%week', MyColumn) > 0
              then 1
              when patindex('%days', MyColumn) > 0
              then 2
              when patindex('%Minutes', MyColumn) > 0
              then 3
         end, 
         cast(substring(MyColumn, 1, CHARINDEX(' ', MyColumn)) as int)
