I"m a relative newbie to apache myself, but I've just dealt with this very issue, adding lists of redirects for a new website.

Assuming your site is hosted on a linux server running apache:
You can add all of your redirects to the .htaccess file located in the public_html directory on your server. When you connect via ftp, enter the "public_html" directory and you should see a file named ".htaccess". If you do not see one there you can create a new text file and save it as ".htaccess"

Then add redirects by listing them in the .htaccess file, one per line, in this format:
(Note that these are case-sensitive, so example.com/page2 is NOT the same as example.com/PAGE2)

Redirect 301 /oldpath /newpath

where 301 indicates a permanent redirect.

So to redirect http://www.example.com/page1 to http://www.example.com/page2, you would add a line:

Redirect 301 http://www.example.com/page1 http://www.example.com/page2

If you're redirecting to a page within the same domain (e.g. example.com) you may also use relative paths, like this:

Redirect 301 /page1 /page2

Then save .htaccess and test your redirect. If anything goes wrong just undo your edits and save the file, or just delete it if there's nothing else there.

Sometimes you may want to use a rewrite rule instead of a redirect to catch multiple files or specific strings, and knowledgeable users can use Regex to add more flexible rules, but in my understanding this is the simplest way to get going with redirects.
