How can I photograph the sun in the afternoon, and why do I see star-shaped rays around it?

I'm trying to photograph the sun around 3 PM with a Nikon D3300. I tried ISO 100, 1/4000s, and f/32, but the sun is still difficult to capture the way I want.

What camera settings or lens/filter setup are needed to photograph the sun itself safely? Also, why do I get multiple star-like rays around the sun (about 14 points) in my photos?

You have already used the "best" settings : low ISO, fast shutter speed and small aperture.

However, you have reached a physical limitation called "diffraction". Take a look at this question : Why do light sources appear as stars sometimes?. Short story : small light source + small aperture = "star" effect.

This image explains it well (taken from https://www.slrlounge.com/school/diffraction-aperture-and-starburst-effects/).Effect of aperture on the star effect

So, if you want to have a "better" picture, (less "rays") you need to use a bigger aperture (probably at least f/11) and use a lower ISO and a faster shutter speed to still have a correct exposure... which is impossible on your lens/camera, because you are already at the lowest iso/fastest shutter speed.

Don't give up yet ! You can artificially decrease the quantity of light entering your camera by using a Neutral Density (ND) filter. Take a look here : What are neutral density filters and how do I use them to create long exposures in daylight?. What you are looking for is obviously not a long exposure but this post provides great information about what ND filter are and how they work.

Your settings are already near the practical limit for reducing exposure: low ISO, fast shutter speed, and a very small aperture. The star-shaped rays are caused by diffraction: a very bright small light source shot at a small aperture produces a “sunstar” effect. To reduce those rays, use a wider aperture such as around f/11 or wider.

If you want to photograph the sun itself rather than just a bright sky with the sun in frame, you usually need a proper solar filter or very strong neutral-density filtration to bring brightness down to a safe, manageable level. A lens alone will not solve this.

Be careful: pointing an unprotected camera directly at the sun, especially with telephoto lenses or a telescope, can damage your camera and lens, and viewing the sun directly is dangerous to your eyes. Use only filters made for solar photography; don’t rely on improvised materials.

For general shooting, aperture priority with negative exposure compensation can help if you just want the sun in a wider scene, but for close or detailed sun photos, proper solar filtration is the key.
