Well, the name I wish I had given my dd (the one I ended up giving her as a middle name) is Isabella. It (and its variants) is a lot more popular now than it was 14 years ago, but I still wish I had chosen it. I envisioned her friends calling her Izzy and her boyfriend/lover/dh calling her Bella as it means beautiful in Italian. Instead, I gave her the silly made up name that will forever date her to the 1990s/turn of the century. 
Oh hang on, I am on this thread to convince the OP that the regret lessens.... 
Slithytove, FWIW, my opinion on your name choices:
Verity - I like a lot and have toyed with choosing for the hypothetical dd2 I will now never have, despite knowing a really obnoxious Verity about 25 years ago.
Hannah - very popular these days, there is at least one in every year of my 3 teenager's years at school. Some nice, some not. Personally, I think it is too popular and not characterful enough for me.
Georgia - could be ok, though I can't get the character from Angus Thongs and Perfect Snogging out of my head (my dd has all the books)
Amy - pretty but quite a weak sounding name
Sophia - classic and elegant but maybe a bit overused these days?
Annabel - always makes me think of the horsey set, which is fine if you are part of that scene?
Claudia - I should feel about this the way I feel about Sophia but I knew a very irritating one when I was at school. Very full of herself, a right madam, so that puts me off.
These are just my opinions though, coloured by my experiences. You shouldn't let anyone put you off the name if you like it. And the one good thing about your list is that they are all proper names, spelt the usual way.
