How can I change the metadata for several images at the same time (batch edit)? For example, comments and titles.

There are two good tools to edit meta-data of image-files:
exiftool and exiv2
exiftool:
You will find exif here: official site
It also has a graphical frontend: frontend for exif
exiv2:
This is a better tool than exiftool. You can find it here: official site.
Here is a man page on how to use this: exiv2 man page
You can try installing gThumb Image Viewer, by typing on the Terminal:
sudo add-apt-repository ppa:webupd8team/gthumb
sudo apt-get update
sudo apt-get install gthumb
