So I was going to remove the crank of my bike but I dont think I can because of this plastic cap. Is that cap there to protect the bolt or is it just a part of the crank itself and I don't actually have to remove it to take the crank off? Thanks in advance!

Yes just pop it out with a flat head screwdriver Behind it will be a socket hex or normal hex head bolt that you need to remove. And then you need a special tool/adapter to pull off the pedal arm. A crank puller or crank arm remover.

After that then you’ll need a crank box remover

Are you just changing the sprockets and pedal arm or the actual crank box in the frame ?
That’s just a dust cover, your need to remove it to access the bolt/nut
I think there is a little crank on your rust
Yes
You are going to need certain tool called a crank puller. Under the plastic cap is a nut to remove, then you would thread on the crank puller. But you’ll need to get the puller specific to your crank. One to use on a tapered spindle bottom bracket. It’s no too hard to damage the crank arm threads if you do it incorrectly so maybe find someone who has done it before.
