Bipper, Nemo, Fiorino are identical B-vans produced by FCA and rebadged as Peugeot and Citroen.
Partner, Berlingo, Combo are identical C-vans produced by PSA for its 3 brands.
Kangoo and Citan are identical C-vans produced by Renault and rebadged as Mercedes.
Expert, Jumpy, and Vivaro are identical D-vans produced by PSA for its 3 brands.
Talento and Trafic are identical D-vans produced by Renault and rebadged as Fiat.
Boxer, Jumper, and Ducato are identical fullsize vans produced by FCA-PSA joint venture and rebadged (also as Ram Promaster)
Master and Movano are identical fullsize vans produced by Renault and rebadged as Opel (probably won't last no Opel is part of PSA).
Ford is currently the largest van seller in Europe but with GM selling out to PSA and now PSA and FCA merging, the van market in Europe is consolidating very fast in favor or PSA. So with Ford and VW now paired up, the van market in Europe is going to be divided into 2 big players and will probably force Renault and Daimler to join forces.
1 Ford-VW
2 PSA
3 Renault-Daimler
