Name the people

[NycLondon]

I saw this picture on the web, on a quite interesting page.
I would appreciate identification of several people. From the 1980s I think.
I know Kenzo, X1, X2, X3, Chanel?, YSL, X4, Sonya Rykiel, Issey Miyake, Pierre Berge, Emanuel Ungaro.

I have already done some home work on the Xs. They are really tough. But I assume they are 'famous" as this picture appears to be a summation of the top in Paris at that time.
All my speculations on X2 have not worked out.

I was lucky to stumble on the answer to my question on another web site!
Bye bye.
