SpaceX Launch of Inspiration4, the World's First Private Orbital Spaceflight!

Astro, please don't ban me.. I just have few questions and really want to know.

I was a space cadet growing up, trust me. But this launch has me questioning the whole thing.

#1- While watching the launch, I get they are seated backwards, but I am confused about their seat belts. There was multiple times when they were showing them and they were loose.

#2 -Still with the seat belts, why are they not locked in with seat belts on a roller coaster ? To secure them in, in case of an event ? - But I guess I could answer this my self as you are going to say the g-force keeps them in place.. but still

#3 - When they launched... and were experiencing g force.. how could their arms and hands move so freely ?

#4 - When they got in to "space" with zero gravity, how come only the teddy bear was moving ... they were in the beginning letting their arms "float" , but their legs were not "floating" and then all of a sudden their arms did not float and they were fist pumping like before.

#5- Can you explain the plastic looking back right behind the rocket, I am sure it is heat resistant...but.. wow..

I am seriously not trolling, and although I was a space nerd growing up, I am confused.

This is a serious question:

These folks are going to be in space for three days, presumably in their space suits. HOW are they going to shit and piss? Do their suits have accomodations for this?

Ah, so you think this private space mission is fake too, I assume? So no one will be able to track it in orbit, right?
