Say you tell git-gui to create branch mybranch, but it already exists. If update existing branch is turned off, it will be considered an error.
If you say fastforward or force, it will move your branch to HEAD (or the commit iou specify). FF means it will move your branch only if it can be done by moving it forward in the commit history. I couldn't find a relevant option for git-branch, so I assume it will do a git merge mybranch --ff-only or similar. Force means to forcibly move the tip of the branch to the new location; for this there is a --force switch to git-branch.
