4th is hops, Humulus lupulus. 5th is bindweed, Convolvulus arvensis School project? Art project? General interest? I like the photography, looks like soft window light.
Welcome to the forum, Olga! 1 - Vicia sp. 2 - Solidago sp. 3 - Chamaenerion perhaps 5 - looks more like Calystegia sepium, - bracts are close to calyx and they are much bigger than bracts of Convolvulus arvensis.
Thank you! It's the task in University to make a herbarium that consists of the angiosperms found in Latvia. You guessed it right with the light, that's the soft light of the cloudy midday ;)) Thank you! It's a pleasure )
