Hi !!
1 =e =nosotros estamos
2 = a = tu estas (accent on the a and u)
3 = c = él esta (accent on the a)
4= b = yo estoy
5 = d = ellos estan (accent on the a)
Hope I helped though I can't put the Spanish accent....
"A él" means to/for him. "A ella" means to/for her- él means "him" and ella "her".
If there name is a common name like Juan they change it to John but if not there parents or they will pick another random name
