Libre office is a pretty good replacement for the Windows office suite, though I will say that Excel is a little nicer than its Libre office counterpart. You could try them out on your current system to see how they work out for you. R has a bunch of linux compatible versions though I am not so sure about Teams being able to run on such systems, there is a possibility that one might be able to run it using compatibility tools like WINE but I do not have any experience with Teams so I cant really say.
Addendum: it looks like microsoft just rolled out a version of teams for linux that is more or less up to speed with the ones for windows. Also important to mention is that there is a possibility that the security systems your organizations use might have compatibility issues so thats something to research and/or ask people in the IT department about.
