1) We were all buffeted by the terrified crowd running.
or
We were all buffeted by the running terrified crowd .

which IS grammatically correct? why?

I believe the second variant is the correct one.

We were buffeted by the running terrified crowd.
The article 'the' refers to the noun 'crowd'.

If you say 'the terrified crowd running' the article would make 'running' a noun, which is wrong. The interpretation that 'running' is used as a postmodifying attribute to 'crowd' is also incorrect because unlike the participles concerned, involved, etc. (the question concerned, the people involved) 'running' doesn't function that way.

Except in the set-phrase 'two days (/...) running.'

I think it would benefit from a comma...
We were all buffeted by the running, terrified crowd.

2)

I've seen people used afftonted and affronting, but which is better here?
Why?

She stared at her rival. - is correct. I don't think 'love rival' is good.
