The first two look like Freesia alba.. The others, no idea

Hello Fons, welcome to the Forum. 

 I agree that the white plant looks very much like a Freesia - but why would a freesia be growing  in Portugal? It looks to be in a wild habitat - a garden escape, naturalised? 

The yellow daisy I  don't know but the last buds seems to be of a Cistus.

  Oron, I knew you would be the man with a great answer. Fascinating to see what plants are naturalising  in other countries. I expect some must be a threat to native plants, too, as  some alien plants can be in any country.

I learn from the Pacific Bulb Society Wiki that " In the monograph, Botany and Horticulture of the Genus Freesia (Iridaceae) published by John C. Manning & Peter Goldblatt in Strelitzia (2010), the species Freesia alba has been included in this species ( F. leichtlinii)  as a subspecies.

Known here as "Cape Weed" and an absolute pest because even mowing won't get rid of it! Fortunately in our climate it is annual but right now a gazillion seedlings are germinating

It's a pleasant weed on our local football pitch surrounds - well, the mowed grassy areas.
