I've separated the jpg's to a separate folder in downloads but don't know how to move the to photos.
You have a Photos Library with pictures in it already, right? and you're using iCloud Photos?
Probably the best thing is to open Photos and use File>Import. You can navigate to the folder, click on the folder, and choose "Review for Import." The "review" is in case there are some pictures that are already in you Library-- so you won't unknowingly be importing a bunch of duplicates. It will give you the option of making new albums to hold the pictures.
Another way (that I usually use) is to select the pictures in Finder, and drag them to the Photos icon. It will ask the same question.
If you are using iCloud Photos to synchronize your Mac Photos with your iPhone, then these pictures will be copied their after a bit.
I hope the pictures are fun!
