Solution 2

Select ID, ISNULL(first,'')+ISNULL(','+second,'')+ISNULL(','+third,'') AS Total_String,
(Case when first is null then 0 else 1 end)+(Case when second is null then 0 else 1 end)+(Case when third is null then 0 else 1 end) AS Total_Int

What have you tried?

Concatenate the columns like below

SQL

SELECT ID, Column1 + "," + Column2 + "," + Column3 ....

In above query you have to check if the column value is NULL(in your case -) & omit that if returns NULL(-). For that you could use CASE[^] statement.

For second query you need to find the occurence of character(,), check this one
Character Occurrences[^]

Now your turn, go ahead. Customize where you want.
