Cecco,
The web site you yourself quoted answers your question (if you really meant "how many LPV approaches are there")
http://www.essp-sas.eu/downloads/xcc...18_10_2012.pdf
There are 18 Airports in France with a total of 21 LPV approaches (Toulouse Blagnac has 4 LPV approaches, 2 airports in Switzerland, and one airport in UK.
The others listed are in Germany and are APV Baro approaches.
