Use of Office on multiple laptops

Hi

I have a Microsoft Office 365 subscription which allows me to install this on up to 5 laptops.

However, our non profit organisation (not eligible for registration as non-profit for Microsoft unfortunately) has purchased 6 laptops for use for the community to support their needs (including writing CVs etc). I use the subscription at home for personal and business needs, would I need to purchase an additional subscription for the other laptops? Like many charitable organisations, funds are tight and in most cases, ringfenced for projects, so I'm trying to keep costs to a minimum!
