You can search the name/number of the package/hotfix you need from the top right searching box. For example, type in 36281 will find cq-5.4.0-hotfix-36281.

For hotfix-36281, it has feature:cq-5.4.0-featurepack-35156:1.1 as dependencies. This means you should download feature:cq-5.4.0-featurepack-35156:1.1 first, then apply cq-5.4.0-hotfix-36281.
Note, if this feels complicated, you may want to open a support ticket to have support engineer guide you. Sometimes, there is a replacement hotfix that will allow you to use one later version of hotfix instead of download several packages. In our example, you can use cq-5.4.0-hotfix-34304 instead of using cq-5.4.0-hotfix-36281 and cq-5.4.0-featurepack-35156:1.1.
