Can I use J-Link EDU for nRF52840-PDK, nRF Connect, please? Is it sufficient? What the J-Link PRO provides for nRF52840-PDK, nRF Connect that the J-Link EDU does not?

Sure, J-Link EDU will work. Even better: you don't need any special HW and SEGGER license if you go with any Nordic Dev Kit (in your case PCA10056 aka nRF52840 Preview Dev Kit) because it has already SEGGER J-Link OB (on-board) integrated and you can use it to program and debug chip on the Dev Kit as well as any Nordic chip outside.
When it comes to differences between SEGGER J-Link EDU and PRO just refer to SEGGER web site and their comparison table, there is nothing specific to Nordic.
That is truly awesome. Thx.
