In general the generator to run a pump should be at least 3 times the nameplate kVA rating of the pump motor. This is because when the motor starts there’s a starting surge which could damage or stall the generator which in turn could damage the pump motor. The corresponding ratings would be

From the information provided, it seems the submerisble pumps are running at below capacity (their running current is below their continuous rating). The 40 kVA horizontal pump is running a higher continuous current than its nameplate rating suggests it should. They should review the suitability of this motor or perhaps there’s a typo.
I would not recommend they procure one generator for all of these loads, but break it down into at least 3 or four generators. That’s because they machines will likely not be all connected at the same location, so there will be a voltage drop running from one generator to too many pumps. In addition, it’ll be easier to get smaller generators than one big one. Finally, they should consider a spare if money allows
