Female face > Fake Twins? Spot the differences...

Hello,
I'm a beginner. I created a scene where I added a few characters. I play with them in order to familiarize myself with the GUI and basic posing.
If I remember well, I think I used 2 G2F models. See the attached screenshot: they look similar - like twins - but you can spot differences on their faces. An obvious difference is the lipstick.I'm not sure if this due to lighting, but the character on the left seems to have freckles, softer eyebrows, and generally speaking a peach skin less bright than the character on the right.
After searching for long minutes, I realized that the differences come from the fact that I applied the Materials "Bree All" on the character on the left. If I applied it on the other character, she gets the same peach and soft look and skin (except for the eyes: the Bree All does apply grey-blue eyes, but I manually changed those eyes to brown).
Here are my questions:
1 - I'm not a native English speaker. What does "Bree" mean? Is it just the name of a version of the G2F character?
2 - I found the "Bree All" in SMART CONTENT > Materials > Bree All (after having selected my G2F character). What is exactly this "Bree All"?
3 - When you face a situation when you have differences between 2 characters and you want them to be similar, is there a way to copy and paste all the "properties" (sizes, materials, outfits, underwear, tattoos, etc.) from one character to the other?
4 - Let's say I want the "peach skin" character on the left to become "my character" and use it in different scenes and poses, while changing her wardrobe, outfits, poses, environment, etc. But I want her to keep who she is physically, with the same body properties (eye colors, skin tone, hair, body proportions and muscle size...), how should I do? Should I save her as a "preset"? How? (please note that I'm not even 100% sure of what a preset really is). What if I want her to be sitting, standing, lying, wearing a pair of Jeans, being in a sofa, etc. How can I make sure she is always available as is? For now, I just save the file to a new name to make I kep her with all my/her settings and I recreate the pose and scene around her... Not the optimal way, I'm sure.
Thanks a lot for helping go to the next step. I'm sure this post will be of interest for a lot of beginners.

1. Bree is just the arbitrary name given to the default texture set that comes with the base G2F female. It follows the convention of giving female names to characters and textures. Similarly, Victoria 6 uses a default texture set called Belle.
2. Bree All simply applies all the default Bree textures to the selected figure, as opposed to individual nodes (parts). It is probably what you will want most of the time and simply change certain settings such as makeup, eye colour, etc. as desired individually afterwards.
3. Yes. In the Surfaces tab, simply select the figure (i.e. Genesis 2 Female) at the top of the list and that should highlight all the surfaces in the list. Then, right-click on the figure name and select Copy Selected Surface(s). With your second figure selected, repeat the process, but then instead of copying, click on Paste to Selected Surface(s). Both figures should now have the same textures.
4. "Should I save her as a "preset"? How?" Yes. Unless the character has\includes morphs (i.e. if it is only textures that are different), save a material preset, giving it a name logical for you. Edit > Save As > Material(s) Preset. (In the available list you will see many other options depending upon what it is you are trying to save).
If you want to save a complete character (with clothing, hair, etc), saving it as a scene subset is what I usually do.
It worked.
3bis. What if you want to copy the hair and outfit at the same time? Or at least from one character to another?
5. I would like to use both G2F and G3F in different scenes, but I would like them to look the same, as much as possible. Can I apply "Bree All" to G3F? If not, is there anything I can do that would give my G3F a similar look than what "Bree All" is supposed to do?
