Question 1 & 2:
Make eyecontact and laugh to her first. When she laughs back or stares at you for longer then 2-3 seconds you approach. (If she laughs back it basically means: 'You can approach me') Back straight and a smile on your face. Say something positive. 'Hey cutie what's your name' Or comment her clothes, her style or the way she dances
Then you tease her a bit, kino to check her interest level and get very close to her, talk in her ears softly, dont yell. When your finishing talking, sniff her neck for like 5 to 8 seconds and lay back with a smile on your face. Most likeley she will ask you how she smells or why you did that. You answer you smell great what parfume? I even told some girls her smell turned me up lmao. Just sniff and compliment her.
You could go for the kiss close too at that point, once you build some rapport, received IOIs, danced for example you could sniff and kiss her cheek and go for the kiss on the lips after you kissed her cheek.
If she stinks you know whatsup directly so a win-win lol
You can check directly for IOI's, if you feel she likes you grabb her hand and move her away from the group. If you smoke ask her to join you for a cigarette for example. Talk about fun things, tease her, show her your in the romantic mood. Dont bore her with work related questions, be a Don Juan.
If you can dance lead her to the dance floor and escalate to making out at that point.
(I love taking risks personally, I touch her, make moves asap to test her interest level, if she refuses, declines or gives me headaches Ill just cut her loose and search for another girl in the club)
3 & 4.
Should I get their number and say I have a after party and text when you are about to go home?
You could, but you should escalate at that point like I said above. The more you escalate, the more she invests the more likeley she will like you, be comfortable with you and go home with you. If you talk to her 2-5mins, number close and leave she wont be invested enough to join. Unless shes very interested or just a cheap slut.

If shes highly interested in you she will invite you herself. You just make her laugh, give her a good time and if shes up for it she will invite you to come over. I think it's better to invite her over when you had a good night with her, it keeps you in control, you lead as a man. You could say 'If you can keep your hands off me I'll invite you for a glass of wine at my place''(offcourse with a ****y big smile on your face) You say that when she showed sexual interest in you, like dancing and making out with you. If you didnt made a physical move yet, just find out what interests her and tell her you got something fun to show her at your place she would like. (art, a movie, your piano hell idk be creative)
If shes very interested, makes out with you and all that, invite her and her friend home and call one of your homeboys for her friend and enjoy. Try to act quickly when she agrees to leave, don't give her time to think it true and remember her ex-boyfriend who she loves. Get your jacket call your friend and leave.
Be Bold
Be Sexual
Be Confident
Don't care about rejection at all, once you are indifferent towards rejections and forget about your ego the games finally begin
Laugh
Have Fun
No girl can affect your mood
