1. She is so pretty a girl.
2. They are so pretty girls.
3. They are so much pretty girls.
What I've read on the web is that sentence 2 is ungrammatical
and just want to know it really is.
... and number 1 only really works if followed by something else:
She is so pretty a girl that all the boys want to date her.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
"She is such a pretty girl" and "They are such pretty girls" both work, but "so" does not.

I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
For no. 3; the pattern is “so + much/little + non-countable noun, and so the sentence 3 is not grammatical. The other one is “so + many/few + plural noun”.
If so, we can say "She is so pretty a girl" is not grammatical, can't we?
