Starting issues 2012 Honda CBR250R no ABS

Ive never owned a motorcycle but aggravated with the parking issues at the chemical plant I work at I bought a 2012 Honda CBR250R used with 9k miles on it. Keep in mind I know nothing about bikes.
The bike ran fine at first but then I laid it down twice. the second time was on the right side but it only stayed down a few seconds and I wasn't driving when it happened ( I am a 5'2" 120lb. woman) I was at a light and in a parking lot trying to walk the bike back. After the second fall I was driving the bike down the road in 4th gear and it felt almost like I downshifted but I hadn't. After double checking my gear I realized that it must have lost power and right after that it died. the battery connection had come loose my husband secured and it cranked back up but has been unreliable and left me stranded several times since then.
I brought the big in the shop and it wouldn't crank but was close to closing time so they put the bike on a battery changer and saw they would look at it in the morning. they did spray starting fluid on it nd it cranked right up so they said it may be a fuel issue. the next morning when they went out there to plug it to the diagnostics it cranked right up. So we weren't able to do it.
the problem continued and I drove it when I could for about a week then It was raining and I laid the bike down going about 10 mph coming around the curve. I wasn't hurt and it wasn't a hard fall but the bike skid acrid the road into the oncoming traffic lane luckily it wasn't hit by a car it scraped the bikes exhaust pipe up a little (it fell to the right side) and broke the back light loose up pretty good. I noticed gas leaking out the side but I had just filled the tank run a mile or two back and the tank was still full when I checked when I got home and it hasn't lost any fuel since. it started back up and I drove it home. it cranked later that day but it didn't crank the next morning and then did again the following morning and ran fine.
What is going on currently and has for the last 2 weeks immediately following the above is this.
I crank the bike whenever I am leaving and it starts right up, it runs great I park it go to work and when I get off the bike won't start. It will turn over and try but won't actually crank. The next day I try again and it cranks right up. The length of time between each crank varies and there is no evident change in the weather that I have noticed when it won't crank. I use premium gas. The last time it wouldn't crank I tried over and over and it would turn over but not fire up. after trying probably a dozen times the bikes dash electrical stuff blinked and then was just blank. I turned the bike on and off and it wouldn't back up. I waited a a few seconds with the key turned off and turned it back on and it came back on. this was before I changed the battery and the battery was weak so it could have just been the battery drained from trying to start it so many times but still wanted to mention in case it was relevant.

Things I've done to date:
checked oil-just changed right before buying the bike
checked batter connection
bought new battry
checked spark plug it looked fine but I cleaned it anyways
bought a fuel pump and plan to clean the shoe when I change it but it hasn't come int he mail yet.

I JUST DONT KNOW WHERE TO START!!! 馃槴 any help would be greatly appreciated.

Welcome to the forum!
First of all, stop using premium gasoline. The bike is designed to use regular fuel. Using a higher-octane fuel does nothing to improve performance and can actually have the opposite effect.
Second. buy a battery tender and keep it hooked up when the bike is parked at home. Something like a Battery Tender Jr. is only around $40 and it will insure that your battery is maintained at full power. It will also make it easier to tell if your battery is having any problems holding a charge.
In most cases the first thing you should do is rule out a battery problem before you start buying expensive parts. It sounds like your battery has been allowed to completely discharge - perhaps more than once - as you've been having this issue. That can damage a battery to the point that it will not hold a good charge. even if the battery is fairly new. Checking its voltage with a $20 multimeter will tell you for sure if it is charging fully and holding that charge.

Are there any specifications on how many counts the multimeter needs to be? & Voltage recommendations for the battery tender?

Battery should read 12.5 volts. Anything 10 or under and you have a bad battery.
Any battery tender designed for motorcycles is fine. Most prefer Deltran's "Battery Tender Jr."
Currently under $40 on Amazon and worth every penny.
The original stock Yuasa battery on my 2011 CBR lasted more than 12 years. Probably because it was hooked up to a tender any time the bike wasn't being ridden.
Hi
Keep in mind I know nothing about bikes.
When you have no idea, start with the small things, and slowly learn a new things. Learning never ends. Do-it-yourself hobbies, contrary to its addictive image, do not save money, it cost money:
  • The cost of tools,
  • The cost of mistakes...
it cost money like any other hobby.
DIY mechanics It's a lovely hobby, but not for everyone.

In any case, you need to have a licensed mechanic you can trust on.
The whole secret to the success of the relationship with the mechanic, and your enjoyment of your motorcycle (which does not break down, and comes to the periodic maintenance when it running good), everything depends on trust.

And regarding the battery, with a voltmeter there are three measurements to do:
1. When the battery is about an hour after charging, it should hold 12.7 volts. But this is not enough to determine that the battery is good, there is another test, test 2.​
2. During startup, measure the voltage on the battery terminals, the voltage must remain above 10 volts.​
3. When the engine is running, measure the voltage on the battery terminals again, and you should get about 14.2 volts (this means that the charging system is normal).​
