if I buy a new fpga, since I broke the pin on the existing one that needed to be raised, is there a file that needs to be inserted into it (fpga) and how can I use which HW

The necessary bitstream is downloaded in the FPGA every time you start DsView. Assuming it's cost effective to buy a new FPGA vs buying a new device, replacing the FPGA is safe to do.
If you have a Dremel tool with a fine tip and a good stereo microscope, you can also probably remove enough of the FPGA package material to expose the pin again. The sliver of silicon inside a FPGA is small, and there is plenty of pin material inside the package. I mean, that FPGA is toast for your purpose anyway, so might as well try to save it. Something like https://www.reddit.com/r/electronics/comments/75wcjb/how_to_repair_an_ic_with_damaged_pins/
For everyone else attempting this modification, be aware that damaging the FPGA pins is a real possibility

is there a difference in the family if this one is from 2013, but I can find it in 2005

Protip: don't buy an FPGA from an Aliexpress seller with 90% rating. Desoldering and resoldering that many pins risks damaging the PCB, and you don't want to discover you got a bad FPGA (or even a different chip with altered markings) after soldering it (and having to remove it again)
Use a reliable source like https://www.digikey.com/en/products/detail/amd/XC6SLX9-2TQG144C/2339919 or similar
But, yes, if you want the device to work as expected, use the exact same device model or you risk that either the bitstream doesn't work or subtle timing differences prevent the logic analyzer from working properly
