Can you have more than 1 pet rabbit in the same hutch?

Yes, so long as the rabbits are bonded (this means they're friends and you can 100% trust them not to hurt each other), they can be kept in the same hutch. Unless you have two females raised together from the same litter, then in order to bond two rabbits you need to spay/neuter them first. Never put two males together if they're not neutered because they could (and often do) fight to the death. Two unsprayed females can also seriously hurt themselves, and a male/female mix will either result in injury or pregnancy. Considering all the needy rabbits in animal shelters across the world, it's not a good idea to bring more rabbits into the world by allowing them to mate.
