Model Danielle Lloyd, actress Jennifer Ellison and former footballers Dwight Yorke and Andrew Cole have received undisclosed damages and an apology from Mirror Group Newspapers (MGN) over phone-hacking.
None of the celebrities were present at London's High Court on Thursday for the settlement of their claims for misuse of private information.
However, lawyer Mark Elder told Mr Justice Mann that 34-year-old Ms Lloyd was "distressed and appalled" to learn that she was targeted.
In addition to the emotional impact, Ms Ellison, also 34, believed the activity had adversely affected her career.
MGN's actions had a "massive emotional impact" on Mr Yorke, 46, which affected his life in many ways and significantly damaged his reputation.
And they had an adverse impact on 46-year-old Mr Cole's life in many ways, including leading him to distrust people close to him.
MGN apologised for any damage or distress suffered as a result of the unlawful interception of voicemail messages more than a decade ago.
Mr Elder, of law firm Shoosmiths, said later: "We're pleased to have resolved these claims against MGN on behalf of our clients.
"Our clients may be in the public eye but they have a right to a private life, which should be respected.
"A settlement has been reached with MGN and our clients are happy with the outcome."
