How to just upload a few songs to my iphone using itunes?

So, my computer recenty broke and I need to get a new one. I have been using my moms laptop until I can fix mine and I recently downloaded a few songs from itunes that I want to upload to my iphone. However, i don't want to upload my moms music to my iphone. I tried unchecking the little boxes next to my moms songs and clicking 'sync' but that did nothing. I also don't want to upload the songs from my iphone to her itunes library.

When i plug in my iphone to her computer, it comes up as "Sandra's iphone" (my mom's). We both have the 5c but its not her iphone! I don't know how to change that though, if that is the problem. I also think it is uploading the content from my iphone (pictures, apps, etc. To her computer. There's nothing I don't want her to see on my iphone or anything but she doesn't want it all on her computer taking up space.)

Someone who knows that they are talking about, please help. The answer may be really simple, but I'm apparently technologically inept. Haha!

Deleted iPhone messages won't stay deleted?

Whenever I delete a message the next time I open the messages app literally everything is gone. The only way to fix it is to turn the whole phone off and then back on, but then everything is back, including the messages I deleted. Messages are starting to take up a huge amount of space on my phone. I've tried syncing and resetting… Nothing works.

I have an iPhone 4 with iOS7.

Hoe to delete documents and data on iPhone 4s?

I looked through the apple forums on this subject but they were confusing and didn't help much, I still have an extra 5 GB that are being taken up by "documents and data" and "other". I've already tried deleting and redownloading my most used apps, deleting almost all of my texts, and restoring my phone from computer backup. Any other options?

Why does my iPhone receive messages late when I'm in a group text?

I have the iPhone 4s with 16g (I have less than a gig left of space) and am on T-Mobile.
Every single time I'm added to a new group text, my phone delays all messages sent to me. Regardless of whether it's another iPhone or if they're on the same carrier as me, none of my messages get to me until an hour or so later.

Is it because I'm low on space? Or is it T-Mobile (probably the worst carrier I've ever had by the way)? Or is it the iPhone software?

I don't know if I should text him again?

This guy that I like gave me his number without me asking, and asked if I want to go on a date with him this weekend, and I'm really flattered, two days ago he said he'd text me yesterday, but he didn't. I texted him about twice yesterday, just saying hi, and on my iphone it said he read both texts, but he didn't reply. Has he gone off me? As I'm not sure what to do if he does, but I I like him. And I don't want to keep texting him just incase he gets sick of it, and ignores me. What do I do?
