How do you approach men nicely?

I’m approaching a hot guy this weekend in my meetup group and I have to talk to him and I’m not sure what to say, as I’ve got Asperger’s and it’s been many years since I’ve approached men in person and I’m bad at flirting. Is it ok to introduce myself and my friends and to ask how his week went and see how it goes from there? He also knows I’ve asked questions about approaching him on here, so I feel slightly awkward too. How do I handle this? I’m new to such a situation.
