1) Swagger- someone who has swag, this cool stylish way about them (usually referencing how they walk, behave (like body language-- like pretty chill), and what they look like/ are dressed. hard to explain but you know when you see it. 
2) Schmuck- a way to call someone you dislike (just a guess)
3) Hafta (think about it...pronounce it slowly)- have to. like you "hafta" (need to) do something.
4) To goof off- to act all silly and not serious.
5) Chillax- to chill, like to calm down and not be so worried, anxious, angry, and etc...
6) Take a hike- get lost, don't really want you here
7) To get a kick out of- to find something rather entertaining.
8) To cram- to try to do something usually done in a longer period time, but instead doing it in a very short amount of time. usually in preparation for something. like cramming (studying) for tomorrow's exam at midnight.
9) Green thumb- to be especially good with plants/gardening. have a knack for gardening.
10) Raise the roof- no idea. perhaps meaning partying like crazy?? You are correct.
11) Wing it- to do something without preparation (and usually hope that it turns out okay anyways). like to wing a test, is to not study for it.
12) Bling/bling bling- means money. can also mean you have lots of expensive jewelry (like silver necklaces, gold chains, diamond ring,...)
13) Have eyes in the back of your head- to be very observant. especially referencing teachers, they know what's going on all around them, there's no way to escape their sight.
14) Creeper- to be stalker-ish, and jumps into other people's business (and very suspicious as to the reason) .
15) Trippin'- it means cool. Not quite 
(non-native, advanced- i hope)
Schmuck is Yiddish in origin, and refers to an unpleasant person.
A green thumb is very good at growing plants.
Bling bling refers to jewelry.
Raising the roof is something for wild parties.
A creeper is a sinister weirdo Perfect definition
Fortunately cramming is something of the past : studying very hard for an exam, usually after a belated start.
Mothers an teachers should have eyes in the back of their heads though they probably won't get a kick out of it , i.e, they won't enjoy the excitement it provides.
Most of these expressions are either known or have similar counterparts in other European languages. Pop songs also help to spread the good word(s). And of course a shift in meaning or emotions is not unusual in slang words . Perhaps the innocent looking 'take a hike' no longer exclusively refers to people on their long walk to Compostela. Haha!
And now my guesses:
- Swagger: behave like the hero in a sword-and-dagger picture
3.. Hafta : < have to Excellent
4.. To goof off : to say or do something stupid Pretty close
5.Chillax : < to chill, to calm down
11 wing it : to leave?
15 Trippin' : used to be attributed to Flower Power children on something stronger than tobacco, but probably this is slightly out of date Thank you for the clarification

I have never ever heard these phrases, except one: "To get a kick out of", in a classical jazz song sang by Sinatra: "I get a kick out of you". I think it is something akin to I like you, you make me happy.
