There are a "few" that you have missed. (See attachment.)

DECODING THIS CHART: This chart has been compacted to fit into 80 columns
so it can be viewed on-line. The first column is the name of the compression/
archiving technique. The next field is the file extension given to the
resulting file. After that are 5 columns each for a different operating system.
Each one of these consists of the name of the file/program to undo the given
compression/archiving style and a letter that tells where the file/program may
be obtained. All symbols and letters are decoded at the bottom portion of this
file.

JPEG - source (Free code) is available in
ftp.uu.net:/graphics/jpeg/jpegsrc.v?.tar.Z. Supports conversion
between JPEG "JFIF" format and image files in PBMPLUS PPM, Utah RLE,
Truevision Targa, and GIF file formats. Contact for more info:
Dr. Thomas G. Lane, organizer, Independent JPEG Group
Internet: jpeg-info@uunet.uu.net
Current version (1/93) is v4.
PKZIP 2.04g is shareware. The Encryption version is freely
exportable to all countries except Cuba,Iran,Iraq,North Korea, the
police or military of South Africa, Syria, and Vietnam. (by order of
the US Government)
Some uuencode/uudecode programs are able to read xxencode files.
Stuffit Lite 3.0 is the replacement version of Stuffit
Classic 1.6 for Macintosh. Stuffit Lite is shareware, $25. Stuffit
Deluxe is the commercial version from Aladdin Software.
Stuffit Expander 3.0.1 is a free version from Aladdin that can
decompress most Macintosh compression schemes. It is available in
the same place as other Mac decompression products.
VMARC, available with the command "TELL LISTSERV AT RPIECS GET VMARC
PACKAGE" from a CMS machine, will decode any CMS terse program. The
PC version of terse is a commercial program available from IBM
directly.
There is a portable 'ZIP' that goes along with unzip50p1 that is
available from wuarchive and other mirrors in the same places as
unzip. (see (B) above)
WizUnzip, WINUNZ20.ZIP in the WINDOWS3 dir on
wuarchive (B), is a MS Windows 3 version of Unzip50p1.
GZIP, the GNU Zip-like utility, is available from prep.ai.mit.edu.
Current version is 1.2.2 (16 June 93). A VMS version is available
as follows: (this has binaries for VMS for VAX and AXP)
To get gzip via anonymous ftp from ftp.spc.edu, you'll need:
[.MACRO32]UNZIP.EXE or UNZIP.ALPHA_EXE
[.MACRO32.SAVESETS]GZIP-1-2-2.ZIP
To get it via e-mail, send the following commands in the body of a
mail message to FILESERV@WKUVX1.WKU.EDU:
SEND GZIP-1-2-2
SEND FILESERV_TOOLS
There is a set of translators that will allow Stuffit Deluxe to read
btoa, UUencoded files, zip, pack, tar, MacBinary, and others. They are in
sumex-aim.stanford.edu:/info-mac/utils/stuffit-deluxe-translators.hqx.
When using tar.exe for PC's, the order of option flags is important.
For extraction, use tar -xvf <filename>.
ARC : From SEA, ARC 6.02 is the latest widespread shareware release.
It is available at A (ftp.cso.uiuc.edu).
Also, SEA has ARC 7.10, but it is commercial, not shareware.
(see note at bottom)
When using binscii.exe for an Apple II, there are different file extensions
depending on the type of file being changed.
BinHexed files (with the extension .hqx) can be UnBinHexed with BinHex 4.0 or
Stuffit (preferably Stuffit). BinHex5.0 format is a MacBinary format,
while BinHex 4.0 files are ASCII format.
The files listed are only supposed to uncompress/unarchive.
To compress/archive, further software may be needed.
USAGE NOTES:
There are certain "standard" combinations of compression used:
unix - .tar.Z
(often this will be .taz for PC's)
unix - tar.Z.btoa (abbrev. to .TZB sometimes) (aka "tarmail")
mac - .sit.hqx
- these must be undone in order starting at the end of the name
Sometimes an archive may be self-extracting. These will look like normal
executable programs. Simply run them to undo the archive.
LZEXE (PC), PKLITE(PC), Imploder(Amiga), and PowerPacker(Amiga)
are executable compressors.
They compress an executable file and attach an uncompressing header so that
the file can still be executed while in compressed form.
The listed programs for these utilities compress files, in order to uncompress
a file with these types of compression, just execute them.
DIET (PC) is a TSR program that compresses and decompresses both
executables and data files as needed.
