My travel date is tomorrow (Friday), train ICE, from Berlin to Paris, (1411 hrs)
Ticket type are
Self: Eurorail global pass (2nd class)
Spouse and kid - 1st class booked from bahn.de
So your options are (someone else correct me if I'm wrong) :
On the 1st train to Frankfurt/Mannheim they may sit with you in 2nd class since reservations are optional (but recommended on such a busy mainline) or you pay 129.10€ upgrade to sit with them.
On the 2nd cross-border train everyone will have to sit at their booked seat. But nothing forbids you to meet each other in the dining car. :)
Another option if you haven't used your pass yet would be to exchange it to a 1st class pass. But then there still is the question of availability on the cross-border train.
