The grammatically correct way to say it is "you and Alli".
The rule is pronouns (you, he, she, it) come first except when using "I" or "me".
Alli = Ali
¿Estás alli?
Esta usted/estas alli? (accents on 'a' in estas/esta; 'i' in 'alli')
in IPA it is [ali]
esta jorge alli?
uuuh. no.
Son alli preguntas?
Id say 115,
estas ayi? (spelt 'estas alli?')
You would say it "Allie." Names are idiomatic, that is they do not typically translate.
Siempre voy a estar alli para usted
iknow but iam not going to say it
