Well the red car is mine, and - as Splitpersonality said - it's only one! The number plate BE 2502 was the private one of Mr. Beutler himself, the number BE 824U was the garage plate of the carosserie Beutler back in the 70ies/80ies. The two different plates TI 7855 and TI 99102 belong both to me and were on the car in 2 different periods. I'm not James Bond, the number plate here in Switzerland is personal and not related to the car. So if you drive 100 cars over 50 years, all these cars are gonna have the same number.
I think that there are some further, not yet known cars, at least 2. Mine isn't a 1954, as reported, but a 1958 (like the yellow one - that's why they are so similar, except for the tail and the dashboard)
