I'm a freestyle instructor at my mountain and I can say it all depends on how hard you try and commit to trying new tricks. If your instructor is good it's possible you could learn all that and more, especially with 2 days of coaching. I've had lessons were kids have progressed astonishingly fast, learning how to do 1's, 3's, and slide rails in an hour, and I've had kids that haven't learned anything because they're too scared to try something new. Definitely try to attempt new things and you'd be surprised by how much you can learn.
