Multiple wires from Panel into same Switch

I just went to go install a ceiling fan, and had to run some wiring to the ceiling as I didn't have an electrical box there before.

Currently from the switch (it is a double-gang electrical box). There are 2 switches in there. I noticed a total of 5 wires coming into this box (and the ceiling fan would make it 6).

So I figured I'd check what else was on this circuit and I noticed,
- Attic Fan
- Bathroom Fan
- 2x Bathroom Track lights
- 1 Closet light
- 7 electrical outlets
- and potentially a jacuisi tub, and fire alarm...

So obviously it is too much. Now my question is, can I run another wire from the panel from a new breaker into that same double-gang electrical box, and have one switch using the existing circuit, and the other using the new circuit. The reason I would like to use that electrical box is because off the one switch, 5 of the electrical outlets are daisy chained, and I would put the ceiling fax under the same one, so it would almost split the load in half...

Thanks in advance!

What is on that circuit is really not too much. It is borderline, but it certainly not overloaded or dangerous. It all depends on what is being plugged into the receptacles.
I will say, adding a circuit though would only help lessen the load and ensure that you won't trip a breaker.

DO NOT add a spa tub or fire alarm system power to this or any other circuit. These items 99.9% of the time MUST be on their own circuit.

Another cable from the panel can come into the same switch box, space permitting. You do combine the grounds with the other grounds but you do not combine the neutrals with the neutrals of the first incoming cable and its loads.
Stick to your lawn watering schedule until it really starts to pour. After the storm you have only the same number of rest days you always had and then you need to start watering again.
