In order:
Alice - Favourite, classic
Isabel - I really like Isabel, but is a v popular name and you will be told it is overused
Charlotte - Pretty. Love Lottie for a nickname
Florence - This name has grown on me over time. Prefer Florrie to Flo as a nickname.
Harriet - Another name that's grown on me. More unusual than your other choices, although fits in with the revival of vintage names.
Anna - Nice enough, but I find it rather boring.
Anya - Fine. More distinctive than Anna.
Martha - Are you in London? Be careful of her name becoming Marfa. That would drive me mad.
Rosie - Much prefer Rose. Rosie seems a bit childish to me.
Annie - makes me think of Orphan Annie. Find it a bit of a non-name, but I know lots of people like it.
Maisie - I don't hate it but I prefer your other choices.
