1a is a Brassicacea [Mustard] it is edible [can't quite remember the name at the moment...] The seed pods are very thin and round, almost like a 3/4" Indian dreamcatcher.....I have some collected seed out of the wild.....[Purple flower stuff] the rest is just sowthistle....
1b is Sowthistle, [Sonchus] which are related to thistles, same family [Astereceae ie dandelion, thistles, etc] I pick these for fertilizer if I see them...very good source of nutrients similar to dandelion, edible too.
2c is Lemon Balm [very pungent, almost an acrid lemony smell when crushed][I will bet a $100!!]
2a is probably Mentha arvensis and Creeping charlie is underneath it or a weedy Geranium.
2b is probably bee balm, have to see when it flowers, small chance it is something like a hedge nettle [which is a mint too]
3 is a Vaccinium [berry] really just looks like Evergreen or Himalayan Blackberry. Raspberry or Blackcap [black/blue raspberrys] have a almost blue-ish stalk and tend to put up stems from one area before spreading. Blackberries will just spread out anywhere they can go with stolons that become rhizomes.
All mint species have square [4 sided stems] that is a dead giveaway to key a mint.
