Coming from a windows machine here. Is there any way that when you click on an app in the dock that is running, it would show the open instances? For example if I have multiple chrome browsers open. 

Currently, you have to right click on an app item and that pulls up a menu with a very hard to read list. Is there some way to show larger information? Or show all the instances of the app?

Maybe this would require some custom dock plugin? Not sure.
