Congratulations on your journey into photography!
I will give you an over-view as a group, even though you requested not to. I think I can give you much value from this way as well.
The color balance on nearly all of this group of photos is towards cyan. If you want more natural skin tones, edit the photos in post, by adding red and some yellow to warm it up. On my camera, I use the Shade setting for preset color tempurture, which adds warmth already. See if your camera has a warmer preset color balance too. You might need to do a custom white balance to get more accurate, or more flattering color.
Watch out for harsh, contrasty sunlight. The deep shadows look unflattering. When the sun is high up, try angling their faces away from the sun, keeping their faces in total shade, or bringing them into the shade.
Direct, on-camera flash will look unnatural or artrificial, since it flattens lighting from coming from near the lens. Try having someone hold a silver or white reflector from a 45 degree angle from the camera to fill in shadows, or use an off-camera flash system from that angle. The larger light source like a reflector or umbrella can give you more natural results.
