Would help to get opinions from some people who havent watched the show as well 
also add names if ive missed any
Oooh, I love Game of Thrones/Song of Ice & [name]Fire[/name], as you can probably tell from my guilty pleasure list! There are some fantastic names in the series. I love how [name]George[/name] RR [name]Martin[/name] takes familiar names and tweaks them to make them a little bit different.
My favourite names of this list are;
[name]Arya[/name] – An [name]Indian[/name] name that means ‘noble’ in Sanskrit. I also like the [name]Aria[/name] spelling, which is Italian.
Brienne – Although if I’m honest, were it not for the character attached to it I’d probably overlook this name.
Cersei – I think this is a phonetically easier spelling of [name]Circe[/name], which is a very pretty name. Too bad the character isn’t someone I’d like to name my child after!
Sansa – Very lovely name that I could see becoming popular like her sister [name]Arya[/name] in the not too distant future.
Not so fond of;
[name]Catelyn[/name] – I don’t think this variation adds anything to the ever-so-lovely [name]Caitlin[/name]
Daenarys – Too ‘out there’ for me.
Margaery – The name [name]Margery[/name]/[name]Marjorie[/name] has always had too much of an ‘old lady’ vibe for me, and not in a vintage chic way. [name]Marge[/name] [name]Simpson[/name] doesn’t help the cause either!
Mrycella – This spelling is less intuitive to me than [name]Marcella[/name]
Here are some others for the list. I’m not sure from your post whether you’ve read the books, so I won’t say who these names belong to unless I know the character has already appeared in the show. My favourites are highlighted;
[name]Alayne[/name] – I’m on the fence about this name. It reminds me of both [name]Elaine[/name] (which I don’t like) and [name]Alanna[/name] (which I really like)
[name]Arianne[/name] – The French version of Greek mythological name [name]Ariadne[/name], the daughter of [name]King[/name] Minos who helped [name]Theseus[/name] escape the labyrinth and defeat the Minotaur. This is one of my favourite names from the book, and quite usable in real life
[name]Asha[/name]/[name]Yara[/name] – In the books, [name]Theon[/name]’s sister is called [name]Asha[/name] rather than [name]Yara[/name]. I think I prefer [name]Yara[/name] as it has the same simple sweet sound as [name]Tara[/name] and [name]Zara[/name]. [name]Asha[/name] is another [name]Indian[/name] name, meaning “wish” or “hope”
[name]Elia[/name] – This is actually a boy’s name in [name]Italy[/name] and [name]Holland[/name], where it is a variant of [name]Elijah[/name]. I think it’s quite cute on a girl, but feels a bit incomplete to me.
Ellaria – Not my favourite, but the character is great.
Jeyne – I prefer this spelling to [name]Jane[/name], which I find a bit dull. Also it reminds me of Jeyne from Firefly, which is a bonus!
Lyanna – Really like this name, and again I think it could be quite usable. I used to know a [name]Leana[/name] in real life who was great, so this name remind me of her
[name]Lysa[/name] – Not really a fan of this one. I don’t think it adds anything to the more common spelling of [name]Lisa[/name], which has never been a favourite name of mine anyway, despite the fact that it’s one of my best friend’s names.
[name]Meera[/name] – This is an [name]Indian[/name] name which means “sea” or “ocean” in Sanskrit.
[name]Melisandre[/name] – A bit too elaborate for my tastes, but suits the character
Nymeria – [name]One[/name] of my guilty pleasures! If I could get away with calling my daughter Nymeria I totally would. I also love the nn. Nym.
Olenna – [name]Olena[/name] is the Ukranian version on [name]Helena[/name], which I think is a bit sleeker, but I like this variation too. Also her character is hilarious.
Osha – Probably one of my least favourite names of the series. I don’t like the way this sounds.
[name]Shae[/name] – Sweet & sophisticated. Another good one!
Ygritte – Fantastic name and character. Anyone that disagrees knows nothing, just like [name]Jon[/name] [name]Snow[/name]! 
[name]Arya[/name] and Sansa are my favorites. I like Cersei but find it less usable due to pronunciation issues.
From the pp’s list, I love [name]Asha[/name], [name]Yara[/name], and [name]Shae[/name]-so cute!
I like [name]Daenerys[/name] and [name]Catelyn[/name] the best.
[name]Arya[/name] - [name]Lovely[/name], but all I can see is “aryan!”
Sansa - I like it, but I’d classify it as GP.
[name]Catelyn[/name] - Ugh. I’ve ranted about this one before, but I think its look and sound are completely out of place in the story–to me, “[name]Catelyn[/name]” sounds like the name of an obnoxious sorority girl born in the 90s whose parents were trying and failing to be different when they named her. Also, if you want it pronounced “cat-lin,” don’t use an E.
Cersei - [name]Kinda[/name] like it. I’d use the Greek [name]Circe[/name] instead, though.
Brienne - it’s just ok.
[name]Daenerys[/name] (nn [name]Dany[/name]) - Really beautiful, but not wearable at all. I’d use [name]Danae[/name] instead.
[name]Myrcella[/name] - Gorgeous.
Margaery - I’ve always disliked this one (though not the character.) It sounds so frumpy.
