Can you help me ID these plants please?

Hello! I have some thing appearing in my garden that I have no idea what they are.
1) This is a shrub? that just sprung up by my back fence in an area with not great soil.

2) This looks like I threw some seeds here maybe. No idea!

3) Some big leafy thing, I don't remember if I had anything in this spot before, could it be a weed?

Thank you very much for any help.

My mother gave me a few chunks of plants from the garden of her new house in autumn when she had to take plants out from a raised bed to deal with a wall being repaired behind it, but she also doesn't know what most of the things are at her place. So the others could possibly be from that. I do tend to just chuck in whatever I get given and then forget all about it.
