There were seven Castle Keeps Gargoyles produced. I don't know if there were any more characters to this line. They don't appeared to have had individual names.

Castle Keeps Gargoyles

The back of the packaging reads:

"The Castle Keep Gargoyles live in a faraway land,
somewhere between the here and there,
wrapped around an age-old castle suspended in the air.

Keeps are soft, puffy little creature friends with tails to fluff.
As for cuddle and snuggles - they can't have enough!

Wee, good hearts that sparkle and shine,
still beat a love message through centuries in time.

Keeps are magical. Special horns atop their head,
tune in to hear every word that is said.
Eyes that glitter and glow so bright,
that they can see far into dark night.

The Castle Keep Gargoyles are the protectors of the Realm.
Our Fairy tail begins just there, with a kind, wise king and a princess fair...
