The first plant is cow parsley. Always be careful with cow parsley as there is an extremely similar plant that is deadly. (Water hemlock)
The second plant appears to be some kind of sow thistle. It is quite hard to tell from the photograph though so I am not 100% sure of it.
As breakawayfromme said, there are foraging and plant identification forums that may be able to help you. There are also plant identification apps and websites. I currently use one called PlantNet that is available as an app or by just accessing their website, just upload an image and it can identify the plant (or get quite close). The only problem with these apps is that you do have to double check everything as they can only be so accurate.
