[name_u]Love[/name_u] [name_f]Coralie[/name_f] so that is my pick, however I do have a soft spot for [name_f]Coralyn[/name_f], it would just depend on how you want to pronounce it:
[name_f]Coralyn[/name_f]: [name_m]Cor[/name_m]-a-lin
[name_f]Coraline[/name_f]: [name_m]Cor[/name_m]-a-leen or cor-a- line (as in the word line).
I prefer just [name_f]Cora[/name_f] 
I prefer [name_f]Cora[/name_f] by itself.
[name_f]Coralie[/name_f], but also [name_f]Cora[/name_f] on it’s own, [name_f]Coral[/name_f] & [name_f]Coraline[/name_f].
I like [name_f]Coraline[/name_f].
I like [name_f]Coralie[/name_f] from your list, but my favorite ways to get to [name_f]Cora[/name_f] are [name_f]Coraline[/name_f] (pronounced -lynn or -line, I like both) and [name_f]Cordelia[/name_f].
I like [name_f]Coralie[/name_f] but not [name_f]Coralee[/name_f] because that makes me want to say KOR-ah-lee not KO-rah-lee.
[name_f]Cora[/name_f] is just gorgeous on its own, though I absolutely love [name_f]Cordelia[/name_f] nn [name_f]Cora[/name_f].
I adore the spunky, sweet, beautiful [name_f]Coralie[/name_f]. I picture such a cheerful, bright, enthusiastic, nature-loving girl/woman.
I would use just [name_f]Cora[/name_f], [name_f]Coralie[/name_f], or [name_f]Cordelia[/name_f]
I prefer just [name_f]Cora[/name_f]. Of the longer versions, [name_f]Coraline[/name_f].
[name_f]Coralie[/name_f] out of the list or [name_f]Coraline[/name_f]
I think [name_f]Cora[/name_f] is fine without any variation.
I voted for [name_f]Coralie[/name_f] but I think my favourites would have to be [name_f]Cordelia[/name_f] or [name_f]Coraline[/name_f]. [name_m]Even[/name_m] just [name_f]Cora[/name_f] is lovely!
I voted for [name_f]Coralie[/name_f] but I actually much prefer [name_f]Cora[/name_f] on its own, or as a nn for [name_f]Cordelia[/name_f] or [name_f]Cornelia[/name_f]
I prefer [name_f]Cora[/name_f] on its own
