The top one is Hogweed (good for feeding pet rabbits) Heraculeum sphondylium (not the same as the poisonous Giant Hogweed)
The second is Alexanders (reputedly brought to Britain as a vegetable by Roman soldiers) Smyrnium olusatrum. Still found growing where there were Roman settlements says a friend of mine who is an archaeologist.
The third is Harts Tongue fern - you were right
And what a lovely woodland.
