Should I help my friends with a company intro?

I got an offer from company A (series C startup) 6-7 months ago when I was doing new grad recruiting and declined the offer. I have two friends who are interested in working at company A. Both are '24 grads (one year above)

Friend 1:

Friend 1 is an ivy grad and (one year above me) currently works at a no-name company B and got to the final round for a Snowflake/MongoDB/Palantir (company A hires quite a lot of data engineers from this company).

Having talked to the director from company A, I think my friend would be a good fit for company A given their career goals.

Friend 2

Friend 2 is also an ivy grad and has a much stronger brand recognition (FAANG intern + works as a data engineer at Snowflake/MongoDB/Palantir). However the role they're interested in is software engineer, which is an adjacent role.

I have contacts for both the HM and the recruiter. My questions are:

1. Should I refer either friend? Is there a harm to refer both?
2. Here's the draft I'm planning to send to the recruiter who talked to me:

Hi XYZ,

I hope you're doing well and it has been a while since we last spoke! I was talking to my friend ABC and I think they're a good fit for the company. ABC previously did <cool thing they did> and when we talked about career aspirations, I thought they might be a good fit due to <specific reason>

I'm wondering if you'd be interested in this friend and if so, I'd be happy to connect you two. I've enclosed their resume below. Thanks and hoping to hear from you!
