A 4x4 should easily hold 4-5 of those plants, so drop the WW, Kish, MamaMia, and Cheese! Four plants is plenty to start and you will get several ozs from each. First time just get into it and you will improve on each successive grow. Don't overwater, don't overthink. Get good soil, germ those babies, and get growing.
That was my first take. Too many seeds. I think 3 is ideal for a beginner, so I would germinate 5. You will probably lose one or two. If you end up with all five, it will still work fine. I'd go for 5 gallon fabric pots as your final transplants.
Get a timer to switch your lights on/off. I have a basic manual one. Less to go wrong.
Since you've already bought nutrients get the FF soil to go along with it. I've not used it, but aside from comments of it being hot for seedlings, it's a well established brand. There are a few types, so make sure you understand which one you are buying, and at what PH you are suppose to water.
Your lights are good. Just use one for veg and early flower. Put the other one out about 2 weeks into flower.
Start a journal. For a beginner that is probably the most important thing you can do. Make up a feeding chart as part of your journal. You have got to write everything down or you will forget to do something at a critical point. When something goes wrong (multiple things will) it really helps to be able to look back. If you want us to look over your shoulder, do one on this site as well. I use a combination of a spreadsheet and Word to create a journal that includes photos etc. It really helps on your next grows to see the earlier ones.
As Blew Hiller said, "... germ those babies and get growing." You'll love it.
