Would it be okay if i danced with this person instead?

my mom and real dad are divorced i haven't seen him since i was 3 years old then once when i was 15 now i am 18 and about to get married. my mom remarried to my step dad and i been callin him daddy since i was 3 because that is when they got married and i was just learning to talk. then they got a divorce when i was 13. my mom then got remarried when i was 16. so since i have a real dad (more like my sperm donor to me) my ex-step dad (to me he is more like a dad than anyone) and my new step dad would it be okay if i danced with my nana (my momma's mother). she i also giving me away because i really don't feel as though i should include my real dad since he wasn't there while i was growing up, or my ex-step dad because he isn't on speaking terms with me or the groom or my "new" step dad since he doesn't know me that well and i would feel totally akward with him. so my question is would it be okay if i danced with my nana for the father-daughter dance which would be more like grandmother-granddaughter dance.
