Missing fonts

In office we have two computers which are both on Mac operating systems with Adobe Creative Design Standard. Computer "A" has all of the fonts we need to create documents. When the same file is opened on computer "B" the font(s) are missing. How can I add the fonts from Computer "A" to Computer "B" so they both have the same exact fonts? It is important because this is our magazine typeface and must be consistent, especially when we are sharing files and making edits. Thanks in advance.

Here are the computer "A" fonts missing from computer "B": Times (T1), ITC Zapf Dingbats Medium, ITS Souvenir Light Italic, ITC Souvenir Light, ITC Souvenir Demi, Helvetica Bold, Helvetica Bold Condensed, Helvetica Light Condensed.
