Can we add custom range in Salesforce Filter?

Filtering options for tables or ranges. You can either apply a general Filter option or a custom filter specific to the data type. For example, when filtering numbers, you'll see Number Filters, for dates you'll see Date Filters, and for text you'll see Text Filters.

I have to display the ouputPanel for each and every user in the org whose role is manager.
I can't assign name of the user directly using text in rendered attribute, since I dont know the names of users in the org where this page will be used.

I want dynamic way where I can render the outputPanel for each and every user in the above mentioned count.
The purpose behind the decrement is, it should cover all the users in the count.
