Take the voltage of the battery before starting the car. Resting voltage of a car battery should be 12.6 volts. If it is not 12.6 volts, I would check the battery connections to make sure that they are tight and secure.

Does the engine turn over slowly are fairly rapidly? If it is turning over rapidly battery voltage isn't an issue and the problem (if there is a problem is some place else). It the engine is turning over slowly there could be a problem with the starter, the wiring from the battery to the starter, battery ground or the battery. It could also be a problem with corroded battery terminals. A lot of good batteries are tossed because people don't diagnose a problem completely. Just because a new battery seems to resolve a problem doesn't mean the battery actually resolved it. The process of replacing a battery may resolve a battery connection issue that could have been cleaned up without replacing the battery or temporarily overcame a high resistance in the starter due to a new battery's slightly higher voltage which will decrease shortly, thus bringing back the starting problem.

Perhaps a fuel delivery issue too besides maybe an electrical one.

More info
The first two or three times I try the start the car - I get almost no response as if the battery is completely dead. Then on the fourth or fifth try it almost starts and by the sixth time, it starts.
Also, whatever gauges I set for the dash layout when the car is on, reverts back to the original setting after I turn off the car.
Any insight? The battery is roughly 3 months old.

Maybe offering a pittance of information would get you more help. Stuff like model year, coupe vs convertible, what transmission, any mods and if so what they are, when did it started exhibiting the symptoms, do you have anything plugged into the OBD port, etc, etc.
So far we have the equivalent of "it's broke. what's wrong?"

Very similar to my 19 Tahoe. My first thought was battery. GM CPO does not cover battery, so I paid $180 out of pocket for an AC Delco with 42 month warranty. No help, car kept sporadically not starting, starting on 3rd or 4th try and finally became no start at all. Tapped the starter with a rubber mallet and it started right up. Dealer replaced the starter under CPO warranty and all is well now.

It sounds like a loose connection. I would double and triple check the battery connections, especially the ground connections. If the battery was replaced 3 months ago, it's possible things weren't tightened down to spec.
It could also be a bad battery (they have warranties for a reason). You can have it load tested at an Autozone.

In my experience, if I haven't driven it for a few days, it usually cranks 2-3 time before firing up the engine.
Once I drive it and make a few stops and then start it up, it fires right up.
On the other hand if I know I won't be driving it more than a few days, I always put the Battery Tender on it.
And whenever I've had the Battery Tender on it, even if its only for one day, it fires right up on the first crank, every time.
YMMV
UPDATE:
Something I found searching for cars with Fuel injectors:
Quote:
"The car engine turns over long before the engine starts.
This is because the fuel injectors need time to spray the right amount of fuel into the right engine chamber.
When the car is first started, the engine is still learning about the amount of fuel it needs to run at peak efficiency."

Well new message
So, a new message popped up: Service: Battery Charging System.
i checked all the connections and they were fine. I started the car with a charger. The battery voltage was around 14. I shut off the car for 1/2 hour. The car wouldn’t start but the voltage was 9 volts. This sounds like a bad battery? Thoughts.
