What are the names of the taiji forms?

What are the Chinese names of the forms in the different forms of taijiquan? I know Chen style has a second form called Paochui, but what about Yang and the others, do they also have several forms?

there is a name for the yang style tai chi form… but it’s a secret.

the 24, 48, 108 etc. don’t have names, other than ‘standard 24’, etc.
