IIRC they usually keep an extra 3 months worth of supplies available at the station, to allow for delays to resupply missions. A resupply mission also arrived at the station recently, which would have had additional supplies for them. If they decide to go with the plan of sending a reduced crew in Crew-9, they'll probably add extra supplies to that too. So, supply wise there shouldn't be any concerns.
