Microsoft Office 2011
That would have to be Office 2010 since 2011 is the Mac version.
But no, nothing you have will run natively in OS X. Just as nothing written (compiled) for the Mac will run in Windows.
You will either need to purchase Mac versions of your apps, or install Windows on your Mac as either a stand alone bootable partition, or in a virtual machine such as Parallels. Doing the latter will allow you to run Windows within the OS X desktop so both are available at the same time. This works well for apps that don't need a lot of system resources, but trying to run most Windows games in VM would be a lesson in futility.
