Can you sync music from your computer to an iPhone?

I have an android. I have over 1, 000 songs on my android. I used an app to download all of my songs and I copied and pasted them to my Laptop just incase i lose my phone, memory card, etc. My question is can you do the same for an IPhone? Do you have to pay for itunes? Can I copy and paste the music from my laptop to an iPhone? Thinking about getting an iPhone, not sure if I want one if I can't have all of my music.

Why is my Wi-Fi signal so weak?

My Wi-Fi router is located in the basement, and everyone upstairs (kitchen living room etc) gets a pretty good for the most part Wi-Fi signal on their phone or laptop/ ipad. I have a bedroom located in the basement, the router as i said was located in the basement and is the opposite end of where my room is. About 15-20 feet away. The problem is that on my iPhone i get little to no signal ( i have a 5S) however its not just this iPhone, it did it with my iPhone 4S as well as my galaxy phone. I have a laptop as well, but it will get perfect Wi-Fi signal while my mobile devices get nothing. If i move my iPhone a little closer to in the direction of the router it sometimes boosts the signal, the weird part is that i only move it like an inch and it gets signal then it goes back down again. There has to be a reason why my computer gets perfect signal and my mobile devices get little or no Wi-Fi when i'm only 15 feet away. And i know i'm less than 25 feet away because my Bluetooth stereo in my room has a 25 foot range and still plays when i'm standing the by the router. This is becoming really annoying as i have to use cellular data even when i'm at home the extra data that i'm charging is really starting to add up. Is there any solution to this problem?

Why did Ex blocked me from iPhone, Facebook?

My ex boyfriend blocked me from everything. Can't send texts, see anything on fbook related to him. The last thing he said was to **** off. He broke up w me then 2 days later called back crying wanting me back so we tried to make it work but he was just so mean and nasty after that. He said I'm too emotional and that I wouldn't leave him alone. I just wanted to make things work and know that I really loved him. He then wanted me to email stuff to him off a flash drive I had of his and I said come pick up your stuff, he said I was mean and never to talk to him again and blocked me. Why?
