I’ve gotten obsessed with this hobby very quickly, and as I just got my first job, I plan on getting 26 different types of tree seeds, with 20 of each type, totaling to 520 seeds. I know that’s a lot, but I know that a bunch won’t survive, and I plan on giving some to friends who are also curious of bonsai. I also have a bunch of room, so I’ll have plenty of room for them to be outside and the indoor ones inside. I’ll put a list of the different types of trees here:Bloodgod Japanese maple tree Lily magnolia tree Waterfall Japanese maple tree Ukigomo Japanese maple Alley cat variegated eastern redbud tree Tibetan cherry tree Pandan screw pine tree Chapel oak tree Purple ghost Japanese maple tree Sugar maple tree Mimosa Persian silk tree Fernleaf Japanese maple tree Fireglow Japanese maple tree Royal poinciana Ponytail palm tree Bamboo palm tree Bristlecone pine tree Rainbow eucalyptus tree Saucer magnolia tree Bald cypress tree Japanese Katsura tree Golden hinoki cypress tree Yama Kagi Japanese maple tree Common juniper tree Flameleaf sumac tree Mountain maple treeI do have to ask, are any of these unable to be bonsai’d? Also any opinions and facts on any of these trees that would be useful to know as a semi-beginner?

You have a large selection of species, but this is not the way to start bonsai. Even if you get some of the seed to germinate it will be many years waiting to be able to do anything with. What are you going to do while waiting? You would be far better buying some plants to work on. They will be alive for a start, and you will have saved 10 years. 
Remember also there are no indoor trees, they may be tropical, but need a greenhouse for protection not a house

You are looking at 5-10 square meters of seed bed. That is a lot. If most of the sprout, you are looking at hundreds of trees.

Maybe a better idea is to get 20 or so seeds and two or three nursery trees, and learn how to keep them alive while the seeds sprout. Then learn how to design and shape the nursery trees while the seedlings grow big enough to design and shape.

I don't know where you live, but have you thought about starting with local species, which you know are suitable for your climate?
