To see a list of possible messages for any given display box object, select Help > Scripting Index and select Display Boxes from the list. Running the Show Properties() command is an alternative to using the Scripting Index. For example, here is a partial list of messages that you can send to an axis:
dt = Open( "$SAMPLE_DATA/Big Class.jmp" );
biv = dt << Bivariate( Y( :weight ), X( :height ), Fit Line );
rbiv = biv << Report;
Show Properties( rbiv[Axis Box( 1 )] );

The following expressions change the font of both axis labels (weight and height in the example above) to 12-point, italic Arial Black:
rbiv[Text Edit Box( 1 )] << Set Font( "Arial Black", 12, Italic );
rbiv[Text Edit Box( 2 )] << Set Font( "Arial Black", 12, Italic );
rbiv[Text Edit Box( 1 )] << Set Font( "Arial Black" );
rbiv[Text Edit Box( 1 )] << Set Font Style( "Italic" );
rbiv[Text Edit Box( 1 )] << Set Font Size( 12 );
rbiv[Text Edit Box( 1)] << Set Font( "Arial Black" );
rbiv[Text Edit Box( 1)] << Set Font Style( "Italic" );
rbiv[Text Edit Box( 1)] << Set Font Size( 12 );
rbiv[Text Edit Box( 1)] << Set Font Name( "Arial Black" ) << Set Font Size( 12 ) << Set Font Style( Italic )
