when you use 'include actual execution plan'
      when we see scans, we can put an index.. what about below:
      
      can you improve on
      PARALLELISM (Repartition Streams)
      PARALLELISM (Distribute Streams)
      Sort
      
      when the cost on these are high?
      is sort related only to ORDERBY or could it be other factors also?

I suggest you read the following to get an understanding of parallelism in SQL Server:
https://www.simple-talk.com/sql/learn-sql-server/understanding-and-using-parallelism-in-sql-server/

SORT is most commonly associated with ORDER BY, but other operations such as "select distinct" or "union" might result in a need to sort the data within an execution plan.
