I wanna ask you, that how many size I can choose for Linux x86-64 root and Linux file system?

IIUC 78.1G are unallocated after deleting sda6 and sda7. You might want a root partition without separating /boot or any other partition from the root directory, this should be the largest partition. You might not need a swap partition, but I'm in favour of swap partitions, the size depends and you probably need a third partition, the EFI thingy. Are you in favour of a file system? What are you trying to achieve? Different to what I've written above and yet somehow the same: https://wiki.archlinux.org/title/installation_guide#Example_layouts
