Answer 1

I assume you'd need to break down the creation of your cell in this format first before applying any style onto it:

                    Cell cell1 = row.createCell(0);
                    cell1.setCellValue("Product Name");

Later,

        CellStyle cellStyle = workbook.createCellStyle();
        cellStyle.setBorderTop((short) 1); // single line border
        cellStyle.setBorderBottom((short) 1); // single line border
        ...//add many others here
        cell1.setCellStyle(cellStyle); //apply that style to the cell

Simple way is to create a cellStyle at first and then just go ahead with numerous cell creations as per the application requirement! Next, just loop into each cell to apply the cellStyle if it is a common behavior that you need for all. Hope that helps!
