Answer 1

i don't know the syntax of tags you made if this is for sql-server it'd be

update table 
set ID=(select rn=row_number() over(partition by ID order by ID) from table)

Answer 2

You mean you want to order the results like that?

Order by SID, ID

Answer 3

You can use the ROW_NUMBER() function with Partition By clause

Here is the sample

SELECT row_number() AS ID, 
    SID, 
    VID, 
    VTXT
FROM VTable;

Partition By enables renumbering of rows in the group defined by each combination of PARTITION BY clause column values.

You can refer to SQL Row_Number samples at referred document hoping to be useful
