Hello macbookboy97,
Thank you for providing all the information you did about what is going on. I found articles that will help with both issues.
I recommend reviewing the following articles for issues with your trackpad on your MacBook Air:

I also found an article to troubleshoot issues with your MagSafe adapter. One thing you mentioned is that both your brother's and your power adapters went out at the same time. I am not sure if you were at the same location, but sometimes line noise issues can cause the power adapter to shut off. I recommend trying out this step:
Identify line noise issues.
Unplug the power adapter from the wall, let it sit for 60 seconds, then plug the adapter back in.
- If the adapter works after this 60-second "rest", you most likely have a line noise issue with your power source. You should reset the adapter periodically by repeating this moment of rest. This issue occurs when the AC adapter's "over voltage protection" feature senses ground noise and then turns off the adapter.
- Some possible sources of line noise include lights with ballasts, refrigerators, or mini-refrigerators that are on the same electrical circuit as your computer. This behavior may not occur if you plug the power adapter into an uninterruptible power supply (UPS) or plug it into a different circuit.
- Unless the adapter continues to exhibit this behavior on a known good outlet, it does not need to be replaced.
If this step does not help, please follow the rest of the steps in the article:
