ELI5: has any civilisation of any size not come up with the concept of names for individuals?

You specifically mentioned a "civilization" which has certain requirements; one of the criteria to be a civilization is that there must be a language system. So, in that regard no; all civilizations have names at some point in their history.

As for any human tribe or colony, we don't really know. It's hard to prove a negative in this sort of case because most of what we know about early colonies comes from written records, which always have names. 

We think even in the most primitive of human tribes, names were created. A particular cry or shout would be someone's name before complex language existed. This can be seen in multiple other species of animals, including dolphins. Hope this helps!

TL;DR: Probably not.
