Let’s say you have a branch r_branch_1

.
First, checkout the remote branch locally.

Check out the branch that has the commits which needs to be copied over.
git checkout branch_A
Now, get the list of commits that you have made on this branch via the git log
command.
git log --oneline
Say you have a new commit on this branch with id 81d3589
.
81d3589 (HEAD -> branch_A) added file2

Keep a note of this commit id and now move onto your second branch.
git checkout branch_B

.
git cherry-pick 81d3589

, upstream
or any other name you have set. REQUESTID
is the merge request id in github or gitlab and BRANCHNAME
is the name of the branch.
