Hellow

This is my first "motorbike" after transitioning from a 2009 Suzuki Access 125. While I am absolutely loving the experience, I have a few confusions that I'd like help with.

1. RPM - On neutral and stationary the meter is usually at 1.5k. There was once after a long drive that I even saw touch 2k. The manual does say between 1-1.5k is normal but what the general opinion and what should I do?
2. Trip F meter - It automatically kicks in when I reach reserve and starts counting. But sometimes, when I've switched the bike off and ride the next time the meter resets. I even experienced it resetting mid ride. Also its not consistent on when Trip F automatically switches on?
3. I dropped my bike twice last month. Just simple imbalance while taking it off a slope. It didn't violently crash but leaned and fell in slow motion 🥲. I noticed after this 2 things and I am not sure if I am just being paranoid - the back brake lever may have bent slightly inwards (can it be fixed?). After a 20km or so ride when I hit the kill switch, the coolant sound would start but it didn't yesterday.
4. Can 1 or 2 happen because of the fall? 🐵
5. I've only done 1.6k km in 3 months, the bottom of the exhaust pipe has started to show corrosion.

Halp 😕 ... Thanks in advance
