Your solution is: 36 AH. With Li, you can consume down to about 80% of total power (28 AH) to ensure a long life.
Basically you need to compare your power usage against your stored energy.
The LED lights are pretty small usage. One could disregard. Unless they are left on for a long time.
A Fantastic fan uses 1 to 3 AH per hour. If you use your fan for 8 hours a day (while you are in the TD), you consume between 8 and 24 AH. On high, that is basically all your battery in 8 hours.
Your other fan will most likely have similar or worse power consumption.
So at low fan settings, you have 14 hours of battery. At high, about 4.5 hours. One or two days power at most. So no glamping for you. One might be looking for 125AH for a better usage range.
Also you need some method of recharging. Obviously the standard charging bases are the best choice. It is not clear if a solar controller could safely recharge these batteries.
Another issue is connecting to the batteries. One might be able to get a connector that can positively connect to the batteries. As opposed to a more standard Li or lead acid battery post system. You want to maintain the connectors on the batteries for charging.
