Ellipsis, late and full

[Jesus]

Hi!, How are you? Well, thanks for helping me with
my english everyday. Thanks indeed!

Questions:

1.- "Ellipsis". Can I use Ellipsis when the sentence
is ironic. Imagine these two sentences:

a.- "I?m dying, dying... to live forever"
b.- A husband to his wife:

"You always come back home...late at night, of course!"

Is "..." called ellipsis here or not?

2.- "You always come back home late"

Can I use "come back late" to mean
He or She has been out all night long
and got home at 4 a.m,5 a.m and so on ?

3.- If I say "The streets are full of people",
Does it mean "There are lots of people
on the street"? Besides,
Can I omit the definite article "THE"?
By the way, Is there another way to mean that?

Thanks in advance!

Have a nice day!

Jes?s
