I for one, can't stand 21" front wheels. 19" or 16" for me. The stem is 1" yes. If you want it to "stick out" you'll either need to rake the neck or use adjustable trees with extended tubes, if you just want it to be longer and sit higher in front, longer tubes will get the job done.

That is a 21 and those are Hydra-glide forks. The ones in your pics are Sportster!

You will need a hub and a complete brake assembly. With a stock round swingarm any type will work but all the correct pieces for the type must be used. There are three major variations, the '58 type with narrow shoes and star hub, the '63 type with wide shoes and star hub, and the '67 type with wide shoes and the so called mid star hub that carries the bearings differently.
So you need to educate yourself before swap meet time!
Don't forget to use the search function on this site. There is a huge amount of archived information available. And use the knowledge base as well!

Raking the neck is done 2 ways, (Neither is a good idea) But one is to cut the top frame tube then heat & bend the lower tubes which increases the angle on the steering head. The other is cut the frame at the steering head & re-weld it at an increased angle and add gusset plates. This was done to a lot of frames back in the 60's & 70's when the fad was long extended front ends. Sadly many frames were done by amateurs without any alignment jigs and were butchered beyond any safe use. The best way to lower your front end is to get a set of "Progressive or Burley" springs and shorter tubes. If you want to run the 21" wheel & want more rake angle use raked trees and Don't chop up your frame.

ive noticed that with the star hub rear wheel the drum sits on the outside...im wondering if this will be a problem if im running a 16x4 rim and 150 tire??? is there enough room??? and if it all good am i looking for a certain size hub for my 16x4 rim or would it be standard like for a 16x3 rim????

If you look back at the original answers for your rim width question you will see an estimated chain to tire clearance. That chain line is standard on all drive trains such as you are proposing for the frame you have. It is the same for all H-D transmission to rear wheel combinations from the '30s to the '90s. The rear wheel sprocket and the transmission sprocket need to liner up, so all rear wheels whether drum brake, disc brake , etc, are all in the same position.
