Hereford have made five new additions to their squad, signing Kingsley James, Rhys Evans, Danny Leadbitter, Frankie Artus and Sam Gwynne.
Ex-Port Vale midfielder James, 21, rejoins the Bulls having made 21 appearances on loan last season.
James has been on trial alongside experienced goalkeeper Evans, 31, ex-Torquay full-back Leadbitter, 22, and former Grimsby midfielder Artus, 24.
Ex-Bulls midfielder Gwynne, 25, agreed non-contract terms for next season.
Hereford-born Gwynne made 69 league appearances for the Conference Premier club between 2005 and 2011, and has since had spells at Westfields, Neath and Brackley Town.
The length of the deals for James, Evans and Leadbitter has not been released by the club and will begin on 1 August, while Artus has signed a season-long deal at Edgar Street.
The new additions mean that the club now have 19 players on their books.
