1. Possibly Misumena viatica, Thomisidae (crab spiders).
2. Possibly a Xysticus species, also Thomisidae (crab spiders).
3. Ach, yes, a weevil (Coleoptera: Curculionidae), what can I say. Way out of my league.
4. Indeed Hymenoptera, family Chrysididae, cuckoo wasps.

I wonder if you wanted to write Misumena vatia?

This possibility is a reality :-), no species to confuse with.

This is a Philodromus (most likely P. cespitum). The family Philodromidae (running spiders) is often confused with crab spiders, because their posture and movements are often similar. But in Philodromidae the leg pairs one and two are not as much enlarged as in Thomisidae. Also they do not have such a triangular shaped opisthosoma (abdomen), ist is more oval.

As SylvainF wrote, this could be a Ceutorhynchus, but most of those species do not have such deep furrows on the elythrae. I think without a look from above and knowing the food plant one cannot identify this weevil from the photo. There are some other genera with look-alikes: Glocianus, Mogulones. Nedyus, Parathelcus, Rhinoncus (maybe more).
