In general, you only want one per drive. It'll have directories for each
OS's bootloader. You have a set of boot variables you set with efibootmgr
that can reference either partition, but you don't gain anything having
more than one.
In general, you'll want to take your free space and make the necessary
FreeBSD partitions, and just populate a directory in your ESP with
FreeBSD's bootloader. You'll want boot variables for both Windows and
FreeBSD. There are examples you can pull from here:

Don't follow the guide verbatim, as it assumes you only want FreeBSD on the
disk and will wipe out anything else it finds, but do look at ESP handling,
general partitioning, and its use of efibootmgr, as those are relevant to
you.
