1) seni seviyorum

2) tatli ruyalar

3) bebegimsin

--------------------
1) sevi = love
yorum = comment
seni = you
So put together it would be "Love your comment." right?

2) Sweet dreams

3) not sure of this one?

1) I love you
3) you are my baby
you got the second one right

Well... I guess 1 out of 3 is better than when I started right?

seni seviyorum = I love you?
I see "you" and "love" but yorum is "I" in this case?
I am going to go study verb harmony some more

Thank you so much!

seviyorum = sev-iyor-um
sevmek-love,to love(take away -mek)
-iyor = suffix for present cont.tense(not finished act)
-um = suffix for "I"(vowel harmony)
bebeğimsin = bebek-im-sin
bebek-baby ("k" changes to "ğ" -look consonants harmony)
-im =suffix for "I"(look pres.cont.tense for "to be")
-sin =suffix for "you" (same as above)

as a begginer I recomend you to look "lessons by qdemir" on this site,it's very simple explanation of how you build sentences in pres.cont.tense.And of course,all other lessons on this site.
have fun with learning
