You cannot mix efi and legacy install in the same disk
You most certainly can as long as you have some way to select the boot
method.
Right.
From a boot system of *another* disk or usb?
From the sams disk or media.
Certainly not a boot system from that same disk, can it?
A bios-grub and a efi-grub residing in the same disk? Possible?
Yes. BIOS-GRUB in the MBR and the BIOS boot partition, EFI-GRUB in the
EFI system partition.

MBR was superseded by GPT.
Both Legacy BIOS and UEFI can work with GPT, and, both Legacy BIOS and
UEFI can be used to install operating systems that can boot on a GPT
drive, where some operating systems (such as MS Windows) are installed
via UEFI, and, some (such as Linux) are installed via Legacy BIOS).
And, current Linux versions can be installed via UEFI...
And, GRUB "happily" deals with them all...
