Each time the new Windows updates are released, part of the updates are for Microsoft Office products. However, every time it pushes product updates and fixes for some products I don't have in my PC (e.g. Microsoft Lync, Outlook).
Should I install updates for those products I don't install at all?

The Office suites contain a lot of shared code. If you see an update offered, it may actually update shared components that are used by various Office applications.¹ An update correcting a bug in the Outlook HTML parser will actually be mentioned as being for “Word”, for example. So yes, you do want to install these updates. Certainly there’s no harm in doing so.
My OneNote-only installation is getting Outlook, Lync and InfoPath updates too, so don’t worry, just install them.
¹Another possibility is programs that are actually included in your SKU, but not installed currently— these get offered because updates get offered per MSI product code— but seeing what products you have mentioned, this is most likely not the case.
