1) Looks like sweet rocket - definitely worth keeping.
2) Looks like foxglove seedlings (on the left) and something else I can't think of right now.
3) Not sure but could be one of the willowherbs - I'd probably have that one out as it looks sick anyway.
4) Geum. If you didn't plant any geums, it will be Geum urbanum (aka wood avens), the invasive weed variety. You could leave it - if it grows small yellow flowers it is the weedy variety and you can hoik it out sharpish!
You can transplant the foxglove sedlings to somewhere you want them to flower next year.
