As each of the list columns has a different structure, you'll have to deal with them in different ways.

With base R:

dfnew <- data.frame(df$Status,
                    do.call(rbind, lapply(df$AuditResult, function(x) sapply(x, toString))),
                    do.call(rbind, df$Deship),
                    do.call(rbind, lapply(df$Item, unlist)))
names(dfnew) <- sub('^.*\\.','',names(dfnew))

which gives:

> dfnew
