Can someone help me identify these uniforms and patches??

I recently acquired a huge lot of WWII uniforms in a rummage sale. I think, about, 30 pieces. Most look like they've never been worn, some are so starched they can stand by themselves.
They all came out of one property in MA and most are labeled as belonging to the same gentleman. But, I'm not a WWII historian but have a fascination with the era, so I'm not too sure how to identify these things. And the last question https://trackeasy.fun/usps/ https://showbox.tools/ http://essaywriter.fun/ I had everyone was so informative, so maybe you can help me out again.

The man's name was Schwarzenberg, and his serial number is stamped everywhere. But, I can't find any information about him.

There's sailor uniforms, white and navy. Two of the navy ones have different patches. What do the colors and patches mean?

Then there's Khaki ones. All with different patches as well. Were these Army? They all have the same serial number inside.
I also have all the pants, belts, ties, hats. Nine yards, all same surname and numbers. Even a canvas bag that has "Schwarzenberg E. W. JR." That's the most identifying I have. Can't find him anywhere.

Then I also have 2 jackets with no stamps. I assume they belong to the same guy. I took a picture of some of the internals of the items because maybe the numbers will be easily identified.
Any ideas?

 

Images would be very helpfull.
