Is there any way to improve the quality of old photos?

I have a sandwich baggy with about four or five micro as cards, plus four old iPhones where I have thousands of pictures dating back to 2008 when my daughter was born. I recently started putting them all in a computer and getting them all in order by dates. My ultimate goal is to start getting them all developed into physical pictures. As you can imagine, the older pictures from old phones, blackberries, iPhone 4 are a lot lower quality than those of my more recent photos on my current iPhone 8. And when you load them onto my computer and can compare them you can really see the difference and the lower quality really shows up when they are seen on a computer screen versus a small cell phone screen. I'm just wondering if there are any ways to improve the quality of some of the older photos to bring them closer to the quality of the more recent photos?

How do I download all of my music onto my iPhone?

So I've been an android user for over 5 years ish now and I've bought music over the years and I've made the switch to iPhone. I've downloaded all of my music onto my iTunes account on my computer and I was able to access it from my iPhone through iCloud. However I want it downloaded onto my phone so that I don't have to be connected to Wi-Fi or data if I want to listen to music out and about. The only way I can see that I can download the songs onto my iPhone is to manually download each song one by one, which would be unreasonable since I have over 2k songs transferred over. Is there an easier way?

Added (1). And the music was purchased through Google Play if you were curious, not that it makes a difference lol

Added (2). Never mind I figured out a trick
