I've been on board Zr. Ms de Buffel. Admitted, this ship was launched in 1864. It is not a sailing ship, but a steamship and a lot larger. The principle was the same, though. Accommodation for the captain was spacious. In fact, I wouldn't mind if my house was that large! The first officer had a large cabinet to sleep in, the other officers had smaller cabinets. I say cabinet, as it looked like cupboards. Everybody else slept in hammocks.
Rezanov may have outranked the captain on land, but definitely not at sea! There is one master on a ship: the captain. Everybody else is either part of the crew or passenger. Even the czar himself would - on board - not outrank the captain. But it would be a very brave (and foolish) captain to go against the wishes of the czar, of course.
The captain's cabin was used for many functions. For example, meetings could be held there. Or, as in this case, the cabin could be split to accommodate high ranking passengers. Very likely this is what happened. Rezanov would have fairly large accommodation for himself. This entourage would be accommodated to their ranks. The ship's officers probably would have to move to smaller accommodation or hammocks.
Scientists and doctors not part of the crew would almost certainly not get a cabin. At best they shared one with another officer, or they got a hammock.
This is to give you an idea. The Buffel was a much larger and far more modern ship. Thus, shorten everything a good deal to get the idea how Rezanov was accommodated. It is highly likely only the captain and Rezanov slept in beds.

Unless someone is fortunate enough to come across the ships plans for the Nadezhda immediately prior to this voyage, I think that any answer is going to be largely speculation.
There are few surviving merchant ship plans so it's difficult to determine reliable averages for measurements such as cabin sizes. In addition, cabin partitions were considered fittings (which could be moved, removed and replaced as necessary) and so are often not rendered on ship's construction plans.
An analysis of 18th Century merchant ship interiors, gives an average of 202 square feet for the captain's cabin (with the largest example being 365sq.ft) while accomodation for the other officers gives cabin (if that's not too grand a word for them) sizes of 25-40 sq.ft.
Let's assume that the Nadezhda was overly generous in her captain's accomodation and that this was maximized for the voyage then we could guess that the total cabin space was ~400sq.ft. split equally between the captain (and his officers) and the ambassador (and his staff). In the case of Ambassador Rezanov, this would mean 7 men working (if not necessarily sleeping) in an area of ~200sq.ft. (10ftx20ft). That might seem large enough as an individual bedroom but as your working space for a long voyage that would start to seem pretty cramped.
