Hi guys I need some help about some questions

Here is the first question , I was on a disco with some friends and we go to a table to one of my friend’s friends , and there was a girl , she danced with a lot guys , she also danced with me ,I wasn’t sure if she was only friend with the guys around her , or if she was with one of those guys , at the end before I left the disco I took her number , and here is my question , do you guys have any ideas how I can ask a girl or lets say whisper in her ear any question that I can ask her if she is with one of those guys or if she is only friend with those guys and if she is single or not ? what question should I whisper in her ear to get that information from her ? this is the first question

Here is the second question , I work out sometimes I go to the gym , and I have athletic body , when I wear t-shirt everyone no matter of gender male or female can see that I have athletic body and I can see that too , but when I wear shirt , girls and guys don’t know that I have atletic body ( or it’s less obvios when I wear shirt than t-shirt ), so guys what is your opinion , what do you think is better for me to wear shirt or t-shirt no matter at which place
Also guys what should I wear let’s say to a first date with a girl ( shirt or t-shirt)
What should I wear to disco ( shirt or t-shirt) which one would be better for pick up at disco ?
This is the second question

Here is the third question , I am 5’7 and some of the girls are lets say 5’5 , 5’6 or 5’7 and they wear high heels so you guys can get the idea how tall they get , and if they act to me bitchy about my height or just mention something about my height , do you guys have any ideas about a negative hit that I can say to the girl of course I will use it only if she act bitchy ? This is the third question

Here is the fourth question , there are 4 situations that I need help and oppionion or suggestions
First situation , lets say that I dance with a girl that I just have met and I have talked with her a little and we just do normal dance , if she dances with me I mean ( normal dance ) does this mean that she is ready to be kissed ?
Same situation but I have talked to the girl 1-2 sentances(we have only exchanged names ) and again just normal dance ? if she dances with me with almost no talk just normal dance “ does this mean she is ready to be kissed “?
Third situation , lets say that I dance with a girl that I just have met and I have talked with her a little lets say 5-10minutes and we do dirty dancing , by dirty dancing I mean she grinds on me and sometimes I gently touch her booty , so if she dances with me ( dirty dancing) does this mean that she is ready to be kissed ?
Fourth situation , same situation like second situation , I have talked to a girl that I just have met by talk I mean we exchange 2 sentaces ( for example we exchange just our names , hi my name is , and she says her name ) and we go and dance and we do dirty dancing , she grinds on me , and I gently touch her booty , does this mean that she is ready to be kissed ?

p.s sorry for my terrible English , I am from Europe , and please tell me to which question you are replying if you cant answer all the questions at once and thx guys if anyone can help me
