I want to make sequence diagram by using UML diagram set in Dia. Can I modify or lengthen the rectangle of the lifeline? When I extend it, only the dashed line that extends.

The dashed line is the lifeline (see here for an explanation). What you want to do is extend the execution occurrence (the wide rectangle). To do this, right click on the occurrence and select "Add connection points".
