To add one contact to a campaign, you can go to the contact profile and select the Communications tab. Next, click on the Campaigns tab, then click on the Add to Campaign button.

Then, you select the campaign you want to add the person to. You can see the campaign summary as well as all the actions to be sent in the campaign preview; you can also select the action you want to start the campaign with.
