Let me help! Hopefully this will clear it up for you. :) Is our meetup still on? = this indicates you are asking if the plans you made in the past will still happen. Example: I called John and asked, "Is our meetup still on? I really excited to see that new movie." John replies, "Yeah man, I'll see you soon." Does our meetup holds good? Does our meetup holds? =These two we would not use or say. They are not grammatically correct or an expression or way of conveying a message. Does our meetup still stands? = Take the s off of stand and this one is also a great way to express your idea. Example: I called John and asked, "Does our meetup still stand? I really excited to see that new movie." John replies, "Yeah man, I'll see you soon." I would most likely ask someone in an informal way: I want to make sure we are still on for.... (our movie plans tonight) or I want to make sure we are still good for.... (our movie tonight). More formally, I would say: I want to confirm our meeting is still set for... (the meeting next Monday.) Hope this helps. Good luck! Let me know if I can help in any other way! :)
