You must create a texture atlas :)

Some tools can do this for you like EZGUI (maybe NGUI too) or you can create your own tools of texture atlas creation.

==> That part of documentation can help you to do this by yourself : http://docs.unity3d.com/Documentation/ScriptReference/Texture2D.PackTextures.html

==> That can help you too but it doesn't rebuilt UV positing of your asset by himself opposite to EZGui atlas building tool : http://pastebin.com/bAz3KFPf
