New telescope user, what are these items for

I attended NYAA Starfest last weekend and ended up purchasing a used telescope, my first, a Celestron NexStar GPS SC goto system with all sorts of attachments, gadgets and gizmos. I have a handle on many of the parts but the attached have me confoozed. Any help appreciated.
What are they, where do they fit and what are they used for?
I should mention that there is also a slough of caps that don't fit anything so it looks like I also collected some old parts from other systems.

A Barlow lens doubles rhe magnification of the ocular lens
The erecting device inverts the image & is used mostly tor terrestrial viewing rather than astronomical viewing.
That's all I know.

Congratulations on your new telescope!
Some of those appear to be spacing adapters. If they are, they help to adjust the camera to gain focusing with your new telescope.
But... like the caps, they may be throw ins to bamboozle you into thinking you are getting more for your money.
Or they may actually work to set the focal length.
Look at Focal Length Adapters and see if anything there rings a bell.

I find that there are usually things included that aren't useful for what you are doing. In some cases, they are for adapting something that you have no use for at all. Just tuck them away in case you ever find a use for them.
