Answer 1

git symbolic-ref --short HEAD should tell you what branch you are on, or print an error if you are not on a branch.

Answer 2

Here's git nthlastcheckout, it gets the exact string you used (or everything after its last space) for your nth last checkout from the reflog:

git config --global alias.nthlastcheckout '!nthlastcheckout'"() {
        git reflog |
        awk '\$3==\"checkout:\" {++n}
             n=='\${1-1}' {print \$NF; exit}
             END {exit n!='\${1-1}'}'
}; nthlastcheckout \"\$@\""

Examples:

$ git nthlastcheckout
master
$ git nthlastcheckout 2
v1.3.0^2

Answer 3

The best solution for us, pointed by @SébastienDawans, was git show -s --pretty=%d HEAD. The output is like remotes/origin/<branch name>, so maybe a cleaning is required, but for our needs it's just fine.
