Remus - not keen
Thomas - really like it
Castiel - quite cool
Bronn - sounds unfinished somehow. Like it should be Bronte but I know that's a girls' name.
Wulfric - not unless you've got some Germanic blood. Sounds odd otherwise.
Ronald - Really don't like it.
Merlin - very cool but I wouldn't quite dare personally
Stanley - don't like it
Rogue - asking for trouble surely! But does sound quite cool
Percy - quite cute for a little kid. Not sure though.
Azazel - no idea how to say this! A-za-zell? Sounds odd. Is it from another culture?
Girls~
Circe - I read a book once where this name was a really evil mythological type character. A witch I think. I don't know if it came from real legend or was pure fiction though. I don't think I like it.
Paloma - quite like it
Sansa - never heard this before. It's ok.
Minerva - not keen
Khaleesi - never heard this before and not very sure how to say it (Carl-ee-see?) Kind of pretty.
It's quite hard for me to pin down your 'type' as some of these names are pretty different from each other. Ummm, how about:
