Sounds like there might be interference among the patterns. Try just one of the
regexps at a time, commenting out the others. But you didn't show any of the
regexps you use, so it's hard to guess. ;-)

It might also be that you need to specify the group of the regexp that you want
to highlight. Here's an example that highlights a group (first regexp line) and
entire matches (other two regexp lines). The `1' says to use whatever the first
group matches.

(defvar shell-font-lock-keywords
  '(("[ \t]\\([+-][^ \t\n]+\\)" 1 font-lock-comment-face)
    ("^[^ \t\n]+:.*" . font-lock-string-face)
    ("^\\[[1-9][0-9]*\\]" . font-lock-string-face))
  "Additional expressions to highlight in Shell mode.")
