Hollyhocks are martyrs to rust - looks a bit like that to me. Anyone else got an idea?
Middle pic looks like scale insects?
Foxglove - could be physical damage - scorched leaf.

Pick off the affected leaves and put in the council bin or burn them. Doesn't look too serious and remember it's very rare to get any plant with 100% perfect leaves and flowers.
