Does it fit a Laban fountain pen?

If the Laban takes normal Euro cartridges then yes the nozzle will be the same_depends how long the barrel is as to whether it can be screwed shut from far end.

Does this fit a Hugo boss fountain pen

I bought this to fit my Parker pen but did not fit. This product is well made and is of very high quality even better then the Parker converter. Luckily it fits well to another of my pen. I don’t own any Hugo pen so if it accepts Parker converter then look for something else.

Will this converter fit a cross atx fountain pen?

I don't know a cross atx fountain pen but if it takes standard cartridges it should work. I bought three and they all work well.

Has anyone tried this specific converter in a rotring art pen? i tried the lamy z28 but the barrel did not close since it gets thin towards the end.

It should be OK in a Rotring as the Art Pen has a longer capacity barrel above the nib unit Lamy's doesn't fit as the ink cartridge nozzle is different size. The Online one is compatible with standard euro ink cartridges which is the same as Rotring. Hope that helps.
