Caution : anywhere within the 2 TiB boundary addressable by BIOS. You
don't have to worry about it with a 2 TB disk (2 TB < 2 TiB).

Yes, partition 2 was probably the previous extended partition containing
the previously logical partition 5.

This is just the default start position proposed by gdisk. Gdisk also
displays the possible start range. I suggest to select the unallocated
sector range 7813120-7815168 (1 MiB) between partitions 1 and 5 for the
new BIOS boot partition.

1 GB is much too big. As previously said, 1 MiB is just plenty.

Actually you don't explicitly install grub on that partition. You tell
grub-install to install the bootloader on the disk, and it will
implicitly find and use the partition.
