Walter B. Gibson is listed as assistant editor on issues 1-9. Although so far I've concentrated on finding Carl Memling's stories, it strikes me that Gibson could have written all the stories in #1-7 as well as "The Fake Bond Swindle" in #9.
Carl Memling turns out to be Charlton's main writer from mid-1953 into early 1955 by cover dates. (He’s well-represented in their horror comics too.) There are other writers; in Racket Squad 13, "Malignant Model Agency" and "The Basketball Scandals" are by the same person, whoever that may be. Ken Fitch is known to have written Racket Squad in 1955-56. Joe Gill starts writing for the title in 1956 (it did survive under the Code) and is its sole comics writer by the last issue, #29, in 1958.
