If you want your HUD element to be on a specific part of the screen, you must set the Rect. Transform to that general location.
In this example, I wanted the weapon HUD to be in the bottom right corner, so I set the Rect. Transform to bottom right.

If you want to hide an element of the HUD, such as the Weapon HUD's semi/auto text, move it to be outside of the UI area (white border).

Your HUD's hierarchy is important to keep in mind. Game objects lower in the hierarchy or children of game objects will display on top of other elements.
For example, if you have some text for your HUD and want a background image underneath it, your text must be lower or made a child of the background object.

If your HUD elements overlay the vanilla game's UI, such as the chat and kill feed showing over the weapon loadout menu here,

you can fix the issue by changing the sort order to be lower than 11.

To convert an image into a sprite, select your image from the project window. Then click on texture type to convert it into a sprite. Open the "Advanced" tab and generate mip maps too.

Mip maps preserve a sprite's look when the sprite is scaled down
