I'll answer here, but note there is a separate JMP Community where more JMP experts will see your questions. Yes, your script is launching Graph Builder 3 times. You need to somehow construct a single script which accounts for the variable number of columns and then run that script. JSL supports that kind of meta-programming (a script that creates another script) using the functions Expr(), Name Expr() and Eval Expr(). Below is an example like what I think you are trying to do.
// a table with lots of columns
dt = Open( "$SAMPLE_DATA/Decathlon.jmp" );
// an expression for the graph's variables
vars = Expr( Variables( X( :Country ), Y( :Score, Side( "Right" ) ) ) );
// an expression for Points elements
points = Expr( Points( X, Jitter( 1 ) ) );
// a loop to programmitically insert variables into those expressions
first col = 4;
last col = 6;
For( i = first col, i <= last col, i++,
Insert Into( vars, Eval Expr( Y( Expr( Column( dt, i ) ), Position( 1 ) ) ) );
Insert Into( points, Eval Expr( Y( Expr( i - first col + 2 ) ) ), 1 + i - first col );
);
//Show( vars, points );
// build the Graph Builder expression from those
gb = Eval Expr(
Graph Builder(
Show Control Panel( 0 ),
Expr( Name Expr( vars ) ),
Elements( Expr( Name Expr( points ) ), Line( X, Y( 1 ) ) )
)
);
//show( gb );
gb; // execute the expression
