Cisse, 30, and Rogers, 27, have both joined on one-year contracts.
Blyth, 28, has agreed a short-term deal after a trial spell.
Bowden, 20, has represented England and the Republic of Ireland at youth level but is yet to play a first-team game.
Head coach Keith Curle told the club website
Bowden has already impressed during training.
Curle said: "Since he came on Monday morning he's trained with us as a group and we can see why he's come with great references and why his club rate him so highly.
"He's extremely confident and comfortable on the ball and I'm sure he'll make the most of this opportunity."
