Is grub on a separate partition?

Don’t get confused by the fact that GRUB has two parts, one in the master boot record (MBR) for the entire disk, and the other part(s) in the partition of the system that has the menu for GRUB. The MBR code connects to the partition with the menu. So, you don’t just do grub-install to a partition, but also to a disk.

Does grub need its own partition?

It is very useful to have /boot as its own partition, since then GRUB for the entire disk can be managed from there. What does it mean: The GRUB on MBR can only load one GRUB (the rest of it) from disk. That specific GRUB (the rest of it) on disk must be configured to find all OSes on the machine.
