It means they are variable stars and are named using a variation on the Bayer designation format of an identifying label combined with theLatin genitive of the name of the constellation in which the star lies.
So:
VY Canis Majoris = VY (Variable) Canis Majoris (Constellation)
YZ Ceti = YZ (Variable) Cetus (Constellation)

Scientists say that VY Canis Majoris is the biggest star we know so basically VY Canis Majoris is bigger than Kolob.
Yes. It is way bigger. The VY Canis Majoris is known to be 1,000,000,000 times the size of the Sun. It's so big that on a scale between the 2 the VY Canis Majoris would almost be a complete rectangle compared to the Sun (and the Sun is as small as a few pixels). The star would reach the top of the screen. Winner: VY Canis Majoris
I have no idea what 1000 cy is
The VY doesn't stand for anything. Before there were telescopes, stars were giving meaningful names, but once the telescope came into play, more stars were discovered than names could be found for. So a number of star catalogues were developed [See related link] to try and get around this problem. VY is just an entry in the Bayer Catalogue for variable stars [See related link]
