Confusing multiple google files

Opening 'startup', I see Google Chrome is active, but looks like this:

Google Chrome(4)
Google Chrome
Google Chrome
Google Chrome
Google Chrome

So, when I open the file location, it only shows 1 google file. It seems, based on my limited knowledge, that there are 5 Google files running, 4 of which are unnecessary. Is that correct? But, if only one Google file is showing in Program Files (x86)/Google/Chrome/Applications, how do I get rid of the other four? It seems like it would be slowing the processing to have 5 redundant programs running.

As far as Google is concerned, you will always see multiple instances even when only one window/tab is open. I have one window of chrome open right now and it shows 8 instances in my task manager.

Each of your extensions shows up as it's own instance in there. And even then Chrome just runs multiple processes anyway.

Thanks. Nothing to worry about then!

Appreciate the feedback.
