These are terrific, Dione! You have a great eye for interesting and engaging subjects and compositions. With the exception of #1, all seem to have spot-on exposure to me.
UHH's download option isn't working at the moment. From the thumbnails it appears the eagle and bears may be slightly out of focus or there was motion blur from slow shutter speed. For moving subjects, I would use shutter priority or manual mode with auto ISO. The reason for auto ISO is in case the critters move into different lighting faster than I can change the settings. See this note by pro Steve Perry:

Under-exposing from what the camera's meter suggested is the most direct and easy way to deal with. For any extreme lighting situation, and particularly when shooting jpg and doing minimal to no processing, always try to take more than one exposure.
If you are in aperture or shutter priority, use EC (exposure compensation) to make the image darker. In those modes you need to be familiar with what setting is being automatically adjusted. In aperture priority, you wouldn't want your shutter speed to drop to where you can't hand hold without movement. And in shutter priority, you may want more depth of field than occurs with an adjusted aperture.
What I suggest for shots where you have
time is to use manual and prioritize your settings. For flowers, my most important selection would be aperture to control depth of field. So I set that first. Then, if there is no breeze and back in the day when I was "steadier" and if I was using a fairly short lens, I could probably get away with a shutter speed of 1/125 second. However, since there is plenty of light for this scene, I instead would set my ISO as step #2 - probably at ISO 100 or 200, depending on my lens.
Now that I have the two most important settings dialed in, I just need to choose a shutter speed that achieves the overall
exposure I want. I might meter the entire scene to get an average exposure, and take one shot with that. Then, I would try to meter on just the brightest white and take another shot with the shutter speed set appropriately (it will be faster, producing a darker image). And I would probably take one more even-darker exposure since digital film is cheap
Note that I am only changing shutter speed. And I am only doing that to make the image darker. If I wanted to do a series with varying depth of field, then I would do a sequence with different apertures while keeping shutter speed and ISO unchanged. In all cases, I change only one setting per "series" and I do it methodically. There are
reasons behind the decisions; nothing is random.
Please be sure to let me know if I've confused rather than aided!
