I'd say that a Demon Lord/Arch Devil/whatever creature of demi god level power in that vein could stop a gate from opening in their palace/whatever they live in, but probably couldn't stop a gate from being opened several miles away. They'd have to be able to sense the magic, and I am unsure if they get to sense everything that happens inside their demesnes.

It's unclear, but I'd say "personal demesne" could be pretty big, and could plausibly include an entire demiplane.
Here's a player-written miniguide to the Gate spell, if that helps.

After reading the spell description and the definition of the word demesne,
"Deities and other beings who rule a planar realm can prevent a gate from opening in their presence or personal demesnes if they so desire."
Demesne: 1. land attached to a manor and retained for the owner's own use.
2. the lands of an estate.
3. ARCHAIC
a region or domain.
or
possession of real property in one's own right.
I would have to adjudicate this to include their castle, lair, or for deities, the entire plane. For lesser beings, I think this would be reduced to the size of their domicile and the surrounding lands they control directly.

Deities could stop you anywhere in their plane/demiplane. Demigod-level beings it would be within a few miles of their castle/stronghold/etc.
If they're not in in their "demesne" it would include anywhere within their immediate sphere of influence. A deity would probably be able to stop you gating in within a few miles, while a demigod might be reduced to line-of-sight, or within the walls of the current building.
Really since this isn't specified, and the beings in question tend to belong in GM-fiat territory, you can decide on the fly what suits the story (unless you're a player, then ask the GM).
