How should I handle my 12year old daughter?

She wants the following for Christmas:
Michael kors purse and watch, a new Iphone, Victoria secret clothes, and a hollister $150 gift card. She is desperate to be popular and is trying out for cheer in April of 2018 but she can't do any flips, she can't jump, she has no friends at school, and she is not flexible. She is so desperate to be popular in school that she wants to copy the cheerleaders and she ditched her best friend who is on the cross country team to attempt to fit in and I really do not like her behavior. A year ago she wanted to be a softball player but she did not try out for the school team because it was not "cool enough." She is very good at softball and cross country. She also has been defiant at home by not doing her chores and she is failing pre algebra. Should I ground her?

Can't text from iPhone

I recently bought an iPhone 7. I can call from it, I receive calls and I receive texts but whenever I try to text someone, the message says not delivered. Most of my contacts don't have iPhones so I can't use I message. The speech bubble is green (which I think means normal sms) but I don't know why they're not leaving.

What's wrong with my iPhone? - 2

I recently just got this iPhone ( purchased from another person ) and it was completely wiped out, mind you I haven't connected the phone yet. So I downloaded the IOS 11.2 on the phone and it's asking for Apple I.D. And password so I'm putting it in and it won't let me in. I know my password and email by memory as it's the password and email to many of my other accounts, and I know I'm not misspelling anything as I'm typing slowly and making sure. I noticed that I couldn t update Game Pigeon because it asked for the previous owner s I.D. And password. I don't know if I have to contact them and ask for their I.D. And password or connect my phone. Also it's not connected but it has the MetroPcs and some bars next to it, I don't know if that s what's affecting my log in. I also can't take off the bars or put it in airplane so it's just my internet server. Can somebody help me please?

If I buy an iPhone from the apple store, will I need to get it unlocked?

Or will I just be able to put any sim (contract or pay as you go) and use it?

Added (1). Sorry, I should of clarified this first. When I say 'buy from the apple store' I mean online. So the phone would get shipped to my house, would I be able to use it with my current sim for example straight out the box.

Is this how people see you?

Okay so you know when you take a selfie with the regular camera on an iPhone or something and it swaps sides? I'm okay with the Mirror image of myself, but when the photo swaps sides is that how people actually see me?

I think I might have been hacked

I have a iPhone 5 and I was on a sketchy website and it redirected my page to a Snapchat add and when trying to exit out of it I clicked a button and it redirect me to Snapchat. Long story short I deleted Snapchat cleared my tabs and turned off and back on my phone. It keeps downloading again by itself. I even disabled AppStore. I think I might have been hacked. What should I do?
