R markdown presentations with output format beamer can make use of
template.texin_header: preamble.tex, before_body: before_body.texand after_body: after_body.texwhich can be implemented in the rmarkdown::beamer_presentation through the YAML-header as follows:
theme: "THEMENAME"
template: template.tex
includes:
in_header: preamble.tex
before_body: before_body.tex
after_body: after_body.tex
Question I: What are the specific purposes of these files listed above?
I got provided with a custom themes for beamer, containing beamerthemeTHEMENAME.sty, beamercolorthemeTHEMENAME.sty, beamerfontthemeTHEMENAME.sty, beamerinnerthemeTHEMENAME.sty, beamerouterthemeTHEMENAME.sty.
Sourcing this template within my YAML header does not lead to the presentation looking too close to any beamer presentation generated straight with LaTex and applying the custom theme.
As an example, in the beamerouterthemeTHEMENAME.sty, a new titleframe is defined, which can then be called at the beginning of the LaTex presentation with \titleframe.
I did not succeed in applying this custom frame-type in the rmarkdown::beamer_presentation.
Question II: Applying a LaTex beamer theme in an rmarkdown::beamer_presentation, which contents to modify or enhance the presentation
beamer theme to template.tex and includessuch that they are applied to the presentation in rmarkdown just as in LaTex?
Question III: Can the final files of the custom theme, the template.tex, and the includes be moved to a sub-folder for the neater organization of the presentation folder and still be loaded correctly

@Samcarter_is_at_topanswers.xyz is right. This is a broad question.
The simplest response is yes, you can use the beamercolor...sty and associated files to create your custom beamer deck. I use RStudio as my R IDE and I wrote a "plugin" that allows me to generate a new custom beamer presentation just like you would generate any other new doc: i.e., File -> New file -> R Markdown -> From Template
I keep the .sty files in home directory I call customtex or something, with a tex directory and a beamer dir.
- companytex
- tex
- beamer [houses `.sty` files]
- latex
When I use From Template in RStudio, these files get copied into the specific location I determine, along with the new .Rmd file that is created.
- reportdir
- .Rmd file
- figure dir
- resources dir
- images dir
- theme dir
- all of my `.sty` files for beamer generation
When I click the Knit (or otherwise run render()), the custom .sty files are used as the template.
