Identification of three spiders in South-West of France

Hi everybody, I took these three pictures recently in South-West of France : picture 1, picture 2, picture 3.

I guess the first one is a Salticide. The second one hasn't a very good quality, sorry. They were respectively 9mm, 6mm and 2cm large (approximatively). The two last ones were close to a river.

Do you have any idea of who they are ?
