1- How can I access to source codes of the GUI file (BoardTestSystem.exe)?

You won't be able to.

2- Is it possible to capture data from FPGA to PC through USB.2 and save it by making a new windows file?

Yes. If you have a JTAG connector, you can implement JTAG communications per this tutorial:

If you need to transfer a lot of data, and your board has an ethernet connector, then you might be better off looking at implementing a NIOS II processor on the board with an ethernet connection to your PC. Altera provide example designs.

3- Can I use bts_ddr2top project to develop FPGA codes and change these codes to match my plan?
--- Quote End ---
Yes. However, what I would typically do is extract the FPGA pin assignments from the provided example designs for your board, review the schematic, and create my own top-level design. Then re-implement the ddr2top design using the Quartus GUI and MegaWizard IP. To determine what was used in bts_ddr2top, open the project in Quartus and then open the MegaWizard, and make a note of the DDR2 settings.
Doing it this way provides you with the insight needed to build your own HDL code from scratch.
