I'd go with
helice for the second one. The third, however, looks very yellow under the forewing for
helice. Did you see the upperside, or are you going solely on this photo for ID?
Here are a couple of
helice from Switzerland, showing the underside of the forewing:
I don't think either is one of the other clouded yellows (in the region,
alfacariensis and
phicomone are the commonest, at different altitudes of course) but the really crucial bits of the wings are hidden in this view.
