Can these pictures be sharper with a different setting. I’ve been setting my SS between 1/1000 to as far as 1/3200 and my Aperture as low as I can, but the sigma 150-600mm does not go below f/5. I adjust my ISO a little but scared to adjust it to high because I don’t want my picture grainy.

the first and fourth look like you have a depth of field issue. They look sharp to me with some softness/blurry in the leaves in the background.

I'd try a few things, keeping in mind that these are differences others are making / doing when you view their processed results as posted to UHH / online.

1, Process your images with commercial-grade software.

2, Shoot in RAW rather than JPEG, especially for options in sharpening and noise processing.

3, Step-down the aperture from wide-open, when possible.

4, Use a single, selective AF point directly on the eye of the animal.

5, Shoot in short bursts (3- to 5-, no more than 10). Select the best of the results later for processing, discard the inferior.

6, Turn off HIGH ISO NR and address noise later in your digital editing software.

7, Turn off Active-D Lighting, especially if changing to RAW.

8, Get closer to your subjects so your can keep this lens in the 500mm range, or less, especially if shooting wide-open rather than in the f/8 - f/11 range. If you need to 'reach' all the way out to 600mm, consider the exposure parameters that step-down the aperture.

For the images where the birds are facing the camera, I see more opportunities in the processing than the exposure / shooting technique. Always shoot only as fast as you need to, where the first image at 1/3200 sec in bright light gives plenty of room for a smaller aperture and / or still lower ISO from ISO-320.

To add to what CHG_Canon said: Be careful with post processing. DeNoise programs can cause loss of detail and sharpen programs can produce unrealistic results

Hello dsims
As an amateur shooter for many years, I conclude that ALL digital pics will benefit from some PP. There are so many facets to the hard/firmware of even the latest cameras and lenses that, given the experience you have, to obtain max sharpness some PP will provide improvement - and this will best be performed on individual pics rather than batch processing.
I downloaded your #4 pic and PP'd it in four different apps using a High Pass Filter Layer. Best result was with Serif's PhotoPlus X8, the fore-runner to Affinity. Close second was EasyPhoto Unblur. Attached is the PhotoPlus X8 version for your interest.

Well, you do not say what camera you are using - and that matters ! In general, I think you are seeing the limitations of this particular lens - especially if you are using a mirror less with no need for micro-focus adjust. If using a camera that can MFA - make sure it is adjusted as good as can be.
The Imatest numbers I have seen for the Sigma C lens suggest it is really best wide open ! - but may be a bit sharper @ 500mm instead of 600mm - try yours and see. "Comfortable" ISO for you will depend on your specific camera but yes, LOWER is always better.

In the OP's original post in the main section, we learned that the camera is a D5600.

Can you tell me what PP is? I feel like it’s kinda like Lightroom and Photoshop.

Hi dsims
PP is photographic short form for "Post-Processing" (after the shot) but is sometimes used for "Pre-Processing" (before the shot). In either event, it describes digitally adjusting a photograph.
Best, D.

You could do even better with Post Processing.
