Kindly let me know how to display this component only once at the top and once at the bottom?

<!-- TemplateBeginRepeat name="Components" -->
              <!-- TemplateBeginIf cond="ComponentTemplate == 'Scripts'" -->

                                <!-- start the code-->
                                @@RenderComponentPresentation()@@
                                <!-- end the code--> 

              <!-- TemplateEndIf -->
 <!-- TemplateEndRepeat -->

If you want to do it in DWT, You can use TemplateRepeatIndex variable for that, It is actually a 0 based Index. So inside the loop 0 would be your first component and 1 would the second one.

Try something like below:

    <!-- TemplateBeginRepeat name="Components" -->
                  <!-- TemplateBeginIf cond="ComponentTemplate == 'Scripts'" -->
    <!-- TemplateBeginIf cond="TemplateRepeatIndex == 0" -->
                                    <!-- start the code-->
                                    @@RenderComponentPresentation()@@
                                    <!-- end the code--> 
    <!-- TemplateEndIf -->
                  <!-- TemplateEndIf -->
     <!-- TemplateEndRepeat -->  

// Your Middle HTML goes here

    <!-- TemplateBeginRepeat name="Components" -->
                  <!-- TemplateBeginIf cond="ComponentTemplate == 'Scripts'" -->
    <!-- TemplateBeginIf cond="TemplateRepeatIndex == 1" -->
                                    <!-- start the code-->
                                    @@RenderComponentPresentation()@@
                                    <!-- end the code--> 
    <!-- TemplateEndIf -->
                  <!-- TemplateEndIf -->
     <!-- TemplateEndRepeat -->

Currently your template is simply looping over all of the ComponentPresentations in the page (or more accurately, the list of ComponentPresentations call "Components". Typically you would develop a .Net based TBB which would first split or partition them into separate lists in the package according to your use case.

Actually, there is easier way. We had similar issue and we did it by specifying exact tcmid of component and template in RenderComponentPresentation function as:

@@RenderComponentPresentation("${FooterID}","${PTStaticCCEmergencyFooterCTID}")@@

Basically, we extract footer id and footer template id via c# block, push them in package and then render explicitly.
