One-line diagram Jockey pump

I know a fire pump has its own service from the utility transformer, but the engineer drew the jock pump as its own service also. The jockey pump is only 20a. Power for the jockey pump can come from any close breaker panel right?

The jockey pump is only there to maintain pressure for the sprinkler pipes, not in an emergency situation; it's normally served from a circuit breaker from the house panel/etc. I have never seen one have it's own dedicated service, but that's not to say there's not a first time for everything.

As already mentioned, yes. I would add though that you could "tap" the fire pump service conductors within the fire pump room and ahead of the fire pump controller and be compliant. There are a number of details though to be aware of in how it is done. Maybe this is what he was thinking?

That's the way we always do it.
