Midfielder Jack Nadin, plus defenders Ben Hammond and David Modupe have all penned new deals.
Modupe has signed a new contract to 2027, with Hammond penning a 12-month agreement and Nadin signing a one-year deal with the option of another year.
Head of Academy Chris McGuane said: "We’re delighted to have rewarded Ben for his hard work with a new contract.
"Ben is a local boy from Nottingham and has been at the club now for 11 years but consistently continues to develop, learn and improve his game."
On Madupe, he said: "David thoroughly deserves the opportunity to extend his contract with us and we are delighted he has signed his first professional contract on completion of the first year of his scholarship.
"David has shown he has real potential as a player and has improved considerably since joining our full time programme at the start of the 2023/24 season. David is a very dedicated person who is always trying to be better each day both on and off the pitch."
And on Nadin, he added: "Jack is another player who has been at the club for over 10 years and we are all looking forward to seeing him improve as a player further as we head into the new season."
