If your hardware supports Mac OS 10.12 or later, I think the sensible thing to do is get a single Office 365 subscription of Office 2019 because it allows up to 6 installs. Office Mac Home and Business 2011 - (1 User/2 Installs) In addition, for a short while Office 2011 was available in the Office 365 subscription program, which allowed for up to 5 installs. This is no longer available from Amazon, but you might find it somewhere else Office for Mac 2011 Home & Student -Family Pack (3Macs/3User) It was also sold as Home and Business with a two license package that includes Microsoft Outlook. Home and Student edition can still be had in a 3 license 'Family Pack.' The answers provided by David and Andre are not correct about how the product was (and in some cases still is) available. Office 2011 was sold in a variety of packages.
