1) Is my goal of 6.5 cm in my femurs relatively safe? Safety is my biggest concern with LL.
With internals, yes.
2) After LL will I be able to work out my legs again like doing squats or being able to jog?
You should be able to. Unless something goes wrong, only some athletic ability should be compromised. Since you're considering Dr. Parihar, he told me I would be able to return to casual sports. Squats will be harder simply because of the long femurs though.
Short femurs favour squats.
3) Do you think Dr. Parihar is someone I can trust with this surgery?
Based on my experience, definitely.
4) What is the time frame for going home, then walking, then normal life?
Probably 5 months. I have a feeling I'll take longer though.
5) Was your life better before or after LL and would you recommended it to others who feel inadequate with their height?
LL was definitely worth it(still in the process), but I was extremely short.
That's hard to answer. If they're already average height or above, it won't be as life changing, objectively.
