Using regular `git branch` command (or appropriate knobs in your UI
front-end if you're using one).
Creating branches is no magic in Git, really.  There's no limits on
how many branches do exist in parallel in a given repository.

No problem at all: you use `git checkout <branch>` to switch between
branches -- this command brings your work tree to the state held in the
tip of the specified branch.

I have a growing feeling you somehow did not manage to grasp the
concept of Git branches.  I hence recommend to *play* with Git creating
a throw-away repository: create a local Git repo, throw a bunch of
files in it, record a number of commits on its default branch,
"master", fork off a "devel" branch, crunch a number of commits there,
now create a "release" branch off the master's tip (using
`git checkout -b release master`), record a number of commits there;
now check out each branch in turn and see what happens, run `gitk --all`
to visualize the situation.  Experiment, that is.  Reading introduction
material and manuals is paramaunt for mastering a tool, but there's no
substitution for practice.

Another thing to consider is to start with readingh The Git Parable [1]
which is the most gentle introduction to Git's approach to managing data
I ever saw.
