Use following steps to create a similar content block for a particular content (Similar contents work on the basis of taxonomy. So first create a taxonomy and assign this to your content type):

1: Create a view with block view.

2: Set field and format setting whatever is your requirement

3: Add a contextual Filters "Content: Has taxonomy term ID"

4: Configuration on this filter: WHEN THE FILTER VALUE IS NOT AVAILABLE - Provide default value - Type: Taxonomy Term ID from URL - under that, check the box "Load default filter from node page, that's good for related taxonomy blocks." - now under vocabularies check the boxes of the taxonomies you want involved here.

5: Now you need to add the second filter in order to exclude the current node from the list by adding "Content: Nid" contextual filter.

6: Set the WHEN THE FILTER VALUE IS NOT AVAILABLE to Provide default value.

7: Set the default argument type to Content ID from URL.

8: Go to MORE at botton , and check the Exclude box to make sure this node is not shown in the list.

9: Move Content: Nid filter to the top position.

10: Save the view and add this block from block list to a particular region.
