Nope.

pkxarc de-arcs .arc
pkunzip unzips .zip
zoo un-zooz .zoo
looz also unzooz .zoo
lharc unfreezes .lzh
melt also unfreezes .lzh
uncompress uncompresses .Z
unpack unpacks .z

There's also comic, but I've never used it, so can't say.

And one or two spiffy new compressors thunk up and added to the confusion
every year.

Right.  Here is some more information extracted from
/pc/ts/tsfaq17.arc available from garbo.uwasa.fi anynymous ftp
archives. 

13. *****
 Q1: What is this file with this .zip (.arc, .arj, .lzh, .pak, .sdn,
.zoo) extension? What am I supposed to do to it?
 Q2: I can't run this file I got with a .zip extension.

 A: This is a total beginner's question, but never mind. One is
supposed to start from somewhere. These files with a .zip (.arc,
.arj, .lzh, .pak. .zoo) are compressed collections of files. You are
not supposed to run a compressed entity (often also called an
archive). You are supposed to unpack it first to extract the files
from within the package. For this you need the relevant (un)packing
program. You can find them in the /pc/pd2 and /pc/arcers directories
at the anonymous ftp site garbo.uwasa.fi, or at practically any fine
bulletin board. (After you have gotten them, they are very easy to
process, since most often these utilities are self-extracting). At
the time of writing this we have eg
  arc602.exe      SEA's .arc packing/unpacking system.
  arj020.zip      Robert Kung's .arj archiver
  lh114b.exe      Dense compression from Japan, (hacked?) version
  lh113de.exe     Latest attested version for .lzh compression
  pak251.exe      NoGate (un)packing for pak, arc, sdn, zip, files
  pk361.exe       This packed and unpacked .arc files fast
  pkz110eu.exe    PKZIP/PKUNZIP "Euroversion" with no encryption
  zoo201.exe      Zoo packing/unpacking facility from Rahul Dhesi
Once you are well familiar with unpacking and packing, there is an
excellent shell for running these utilities. It is called SHEZ and
is in version /pc/pd2/shez59.zip at the time I wrote this item.
   Another advanced feature once you get the hang of this, is that
(most of) these are available in the Unix environment, as well. See
the /unix/ts directory at garbo.uwasa.fi archives for the Unix
versions.

Bzzt! Thanks for playing, though, Jeff!

.ARC files are unpacked with one of the following:

ARC from System Enhancement Associates (the political wrong choice)

PKUNPAK from PKWare, the Phil Katz concern (politically correct ;-)

PAK from No-Gate Consulting

(PKPAK and PAK also create ARC-compatible files)

All 3 are shareware. Be warned, though, that the _new_ version of ARC
from SEA is _not_ shareware, not compatible with earlier releases, and
not unpackable except with their program. (as far as I know, it's also
not selling very well, but that's what they get for being
litigation-prone, IMHO)

LHARC creates files with the extension .LZH

My apologies...you are correct.
