How old are you? The names you list I would put down as fairly middle class/posh (MC in the UK sense which is completely different from American middle class). In other words, those would be quite unusual. 20 yrs of living here & I've known 2x Penny's, no one else with OP's names in England.
I would think of these as much more common contemporary adult woman English names than those you list:
Sarah, Jackie (Jacqueline), Gill (Gillian), Kirsten, Jennifer, Christine (but not Christina), Karen, Catherine (Kate), Helen, Melanie, Julie, Paula, Nicola (Nic, Nicky), Gabrielle, Georgina, Angela, Isabel, Shelia, Siobhan, Annabel, Beatrice, Wendy, Amanda (Mandy), Olivia... oh, and did I mention: Sarah?
