(1) Disk Format refers to the underlying image disk format. That is, the format of the file containing the image data. The Container Format specifies whether that disk image file is contained by another file that may also contain metadata about the image. Here's some documentation you may want to read.

(2) queued means the image was created but no data uploaded whereas saving means image data is being uploaded. Docs

(3) The storage repository is where the image data is being kept. Glance supports several storage repositories and the deployer may choose whichever fits best in its infrastructure. Docs
