I hope your friend did this with your permission and this wasn't manipulative, no matter how well meaning. Honestly, if he introduced you as Aiden, then it probably wouldn't fly without explanation to present as female. If you be yourself and use your preferred name and pronouns, you'll out yourself perhaps, but it could go really well. If you have secondary reason to be anxious in edition to meeting, such as fear of being outed to other people (I don't know if this is a concern in your situation, just including it), you might have to avoid the situation all together.
If you do hang out with this guy and choose to present as male, I don't know what advice to offer other than make your preferred pronouns clear if its an issue, make your name clear, and be yourself. If he is hostile or disrespectful, he's no loss. If he's a decent and respectful person, then you've gained an affirming friend.
I hope you come to a point where you can be out and be yourself, and it should be on your terms. I'm not out to anyone but my SO and a few friends, and I've been having the same struggles of deciding with whom/when to present as male or revert to female. But it is such a relief to be myself with the people who I am out to. I hope this goes well for you, whatever you end up doing
