To see what particular versions are available to you via yum you can use the --showduplicates switch.

httpd.x86_64                        2.4.10-1.fc20                        updates
As far as installing a particular version? You can append the version info to the name of the package like so:

$ sudo yum install <package name>-<version info>
For example in this case if I wanted to install the older version, 2.4.6-6 I'd do the following:

$ sudo yum install httpd-2.4.6-6
You can also include the release info when specifying a package. In this case since I'm dealing with Fedora 20 (F20) the release info would be "fc20", and the architecture info too.

$ sudo yum install httpd-2.4.6-6.fc20
$ sudo yum install httpd-2.4.6-6.fc20.x86_64
