You have been busy!! Won't be long before you'll be able to build you own one.
The attached link may be of interest.

Your first picture in this batch looks like it may be a "quick release" coupling for air or liquid, maybe used to charge an air tank in the rocket or for filling it with a fuel.
Not sure about the next two pics but the last one certainly looks like the end of a pipe where the fitting has been removed/ripped off.
As SG500 says you may one day have enough bits to build your own rocketroud:
