my try of the first two:

all the steps that I take lead to roads with you
whatever I do I still can't give up on you
whatever I do and think you're still on my mind
I've loved you so much that I can't dig you out of my mind and heart

it's the air of this city which suffocates me...

with every new day being born I was born with you again
I'm remembering how many things I've lived in my short life relating to you
which things my stone heart has given up for this love... yes I said my stone heart
this heart, which before meeting you didn't have anything to do with passion, learned to love with you
lived so many things...
when you left learned for the first time what pain means
my heart felt pain

my passion starts with an epic poem, ends with passion

I want to be yours, will you be mine?

Father

babies don't cry after the dead (can they)
they can't beg don't go father (can they)
children can't forget their father (can they)
is your leaving without a return like that, father

they said about a gravestone here's your father
I cried, they have always handed your picture to me
I asked for it's remedy, they said he won't come back anymore
is your leaving without a return like that, father

if I call out you can't hear my voice (can you)
a month passes a year passes, you can't wake up (can you)
you can't hold my hand when I need (can you)
is your leaving without a return like that, father

as a child I've lived your longing
I've filled my yearnings with my mother
I've always told her my dreams
is your leaving without a return like that, father

according to the dictionary "hem... hem..." means "both... and..." (two things at the same time).

I'll try but it may not be 100% precise:

hello, I don't know what to say, I've got angry with him/her saying why are you speaking like that, when I listen to you, you are right, when I listen to him/her s/he is, probably it's better that way, I'm sorry you've broken up, we have a saying- out of sight out of mind (or: what the eye doesn't see the heart doesn't grieve for), take care.

does this make sense?

I'm saying again I'm sorry, call me as much as you want I won't answer the phone, I've told you to write a message to me, I love you very much my love, I love you the way you are.

I think that's because there's uncertainty in the statement (s/he doesn't know what s/he'd said)

I'm not an expert but I think that it's because the condition is clear from the verb and I think it wouldn't be wrong if you use "eğer" at the beginning of the sentence.

in this context it means "either... or..."
etiher death or living
