What does "it's not a vibe" in this context mean? Traffic was really bad. I couldn't even get my drive-thru coffee. It's not a vibe Thank you

Hi please help I don't see myself being in this career for longer than another six months Could you explain this please

What does "easy" mean in this context? Glancing back, I got my first clear look at the monster. He was seven feet tall, easy, his arms and legs like something from the cover of Muscle Man magazine—bulging biceps and triceps and a bunch of other ’ceps, all stuffed like baseballs under vein-webbed skin. He wore no clothes except underwear—I mean, bright white Fruit of the Looms—which would’ve looked funny, except that the top half of his body was so scary. Coarse brown hair started at about his belly button and got thicker as it reached his shoulders. Does it mean: 1) Relaxed 2) Easy-going 3) Cold-blooded 4) Stupid What does it exactly mean? Thank you in advance!
