Chalices are difficult because generally if they didnt come with a name the probably dont have one...
I do like the looks of 2nd one in the first pick though!!!
I also think the bottom on the first picture looks promising. Chalices can only really have a name when you got it. Some chalices have been around for awhile and have such a look that it's un-mistakable like bubble monster, hollywood stunner or some have a common name for a chalice group like mummy eye or watermelons. Hard to tell in your pictures if yours would fall in the common name group.
