Those involved included Melanie Chisholm, or "Sporty Spice" from the well-known girl band, actor Keith Allen, and Shane Lynch from the band "Boyzone".
Katie Major, from law firm Hamlins, said Chisholm, also known as Mel C, said the phone-hacking - illegally intercepting voicemail messages - had caused her considerable distress.
Chris Huhne, a former energy minister, said he had been targeted by NGN to destroy his career because he had called for a police investigation into hacking.
NGN said it strongly denied that there was any corporate motive or direction to obtain information unlawfully.
"Huhne was a senior politician and stories published were legitimate and in the public interest," NGN's spokesperson said.
