Championship side MK Dons have signed winger Dale Jennings, forward Simon Church and goalkeeper Cody Cropper.
Ex-Bayern Munich and Tranmere man Jennings, 22, was available after leaving League One Barnsley following four goals in 47 league games.
He and former Southampton youngster Cropper, also 22, have signed one-year contracts with a 12-month option.
Wales forward Church, 26, has agreed a two-year deal after leaving Charlton, where he scored 10 goals in 63 games.
MK Dons boss Karl Robinson told the club's website: "This is an opportunity for Dale, who knows he's got work to do, but we all saw last time what he can do - he lifted the team and contributed to some good results."
Jennings added: "I'm really happy to be back. I enjoyed my time (on loan) a couple of years ago and it was a no-brainer to return - I can't wait to get going again."
Church has 29 international caps, the most recent against Cyprus last October.
"Churchy is a really top lad, a good player and can score goals. He will add tremendous quality to our team," said Robinson.
Meanwhile, Dons goalkeeper David Martin has signed a new two-year deal at Stadium:MK.
The 29-year-old, who made 47 appearances for MK Dons last season, had been out of contract this summer.
