Based on your description, this would be 5 separate requests with Gmail processing the 5 requests separately. It would be like opening 5 different tabs, and going to the same website on all 5 of them. The webserver would treat each tab (or request) differently. I don't believe servers "combine" multiple requests, if that is what you are asking about.
