Of course If the flue is sized properly
If your furnace is less then 50000btus then yes.

No, you cannot use the same vent for a gas water heater and a gas furnace. Each appliance typically requires its own dedicated venting system to ensure proper exhaust of flue gases and to prevent the risk of backdrafting, which can lead to carbon monoxide buildup. It's important to follow local building codes and manufacturer recommendations for venting to ensure safety and compliance. Always consult a qualified professional if you're unsure.
To seal a gas flue from a furnace, first ensure the flue is properly disconnected from the furnace. Use high-temperature silicone sealant or a metal flue cap to cover the opening, ensuring it is airtight to prevent gas leaks. Additionally, inspect the area for any cracks or gaps and seal them with appropriate materials, such as metal tape or a chimney cap, to ensure proper sealing and safety. Always follow local building codes and regulations for gas appliances.
The concentration of carbon dioxide (CO2) in the flue gas is typically measured to determine the efficiency of a gas furnace. By analyzing the presence of this gas, technicians can evaluate how effectively fuel is being burned and whether any adjustments are needed to optimize efficiency.
The typical flue gas temp at the inlet to the air heater is about 650-750 DegF range.

a direct vent water heater is more fuel efficient (cost's less to operate). aside from that there isn't much difference, aside from not needing a double wall flue through the roof on a standard gas water heater.
If both fireplace and furnace are BOTH gas, if the flue has the correct size, AND if your building code permits, yes. If furnace and fireplace are different fuels, no. Check with your local building inspection department.
