Question

how to set read only properties to the particular info path form control based on user logged in?

Answer 1

Your best option (assuming you are using managed code) is to get the user name with either Application.User.UserName or HttpContext.Current.User.Identity and then call IsInRole (I believe it is a member of the WindowsPrincipal class).

Save the result into the value of a field and you can then use the standard conditional formatting to lock the fields you don't want the users changing. I also usually conditionally change the look of those readonly fields (grey background fill etc) so the users don't get confused and think they can edit.
