Genetic relationships. If two languages are known to descend fro a
common ancestor, then they are part of the same family. If a language
has no known relatives (like Basque), it is a family of one.

I don't recall enough about your projects to say, but if they are
supposed to derive from a common proto-language, then yes.
Otherwise... no.
In either case, though, yes, borrowing does count as language contact
(or rather, is evidence of language contact).
