Welcome to Epic Ski, and welcome to what will hopefully turn into a life long passion for the sport of skiing. As far as the snow is concerned, I see that they've received about 9 inches of new snow, and it appears that it's spring skiing conditions. Meaning, overnight temps fall below freezing, and during the day, temps are well above freezing. I'm making a bit of an assumption as far as defining the types of snow you have indicated, but, here goes... Hard powder---probably groomed by machine which will leave the run looking like a pair of corduroy pants. Or it could be ungroomed, and the snow has been packed down by skiers and snowboarders. Us westerners often call this "crud." Wet powder--- perhaps they are indicating that the fresh snow that fell had a lot of moisture in it. The kind of snow that's good for building snowmen or having a snowball fight with some friends. Powder Slush--- often at ski areas, even though you're on a down hill slope, there are depressions or low spots where the snow will partially melt creating a pool of waterlogged snow. Ice---this is not ice in the truest sense of the word, unless there is a puddle of water that has completely frozen over, but rather hard packed snow. It is a condition of the snow created by repeated grooming and skiers and boarders riding over it. In the mid-west, where I live, the hard pack, often called "boiler plate," is the type of snow I ski on most of the season. The temperatures are still well below freezing during the day, and even when the sun is out, the snow never softens up. Just too cold for that to happen. Often, the snow is so hard, that when you stop for a minute and want to stand you pole up, you literally have to pound it into the snow with a closed fist. Hard pack skiing makes for very fast conditions, although each type of snow presents it's own challenges.
How much skiing you do during a single day will depend on your fitness level and how you acclimate to higher altitudes, not to mention you will probably be sore if you've never skied before.
Since you indicated you were a beginner, I would highly recommend taking a lesson from one of their ski school instructors, unless the person/people you are going with are willing to dedicate their time to teach you, and more importantly, keep you safe. I think back to my first time skiing with some friends. The took a whole 10 minutes or so teaching me to do a snow plow or wedge, and then they were off. It was up to me to try to keep up with them, which I couldn't, and the whole experience was a miserable time filled with fear and frustration, and falling down more times than I can count. Also, don't be bullied or persuaded to ski runs that are beyond your skill level. Stick to the beginner area and enjoy the scenery of the beautiful place you will be at if you decide not to take lessons. It is not my intent to crush your enthusiasm, but becoming a good skier will take time and practice. It's not going to happen overnight. Your safety and proper instruction should be your main concern. I wish you the best, and hope you have a blast!!!
