So i bred 2 giant danios in a 10 gallon and saw a ton of eggs- i removed the parents. I also did a 40% water change that day and after that, still saw most of the eggs. To my surprise, I also saw some red cherry shrimp babies as well as microscopic life that look like daphnia whizzing around. They day after, I can only see 2 or 3 eggs and can't see any wrigglers. What could have happened?

Did you put cherry shrimp in there? It's possible they could have eaten the eggs or the eggs were not fertile and are rotting away.
The tank used to be a cherry shrimp breeding ground and I thought I had eradicated all of them. I could try and move them now but they are quite small and I don't want to disturb the eggs. There were a few white eggs but most were clear.

I was just fishing the baby shrimplets out when, WHAT! A bunch of fry swam in the mug! Now every mug of water I take, there is always fry in them. Well, that has relieved me. One question; are giant danio fry big enough to eat bbs? I would gander they are, but I will wait a day before feeding them as their yolk sac is still there. Phew :)

I’ve never fed bbs. I’d guess they can eat them since that seems to be a very popular first food choice for many.
I personally just use a pistol and mortar to grind up flakes and pellets to feed fry.
 
When danios hatch (even giant ones) they're super tiny and basically transparent. Before free-swimming they'll stick to whatever they can to stay hidden. Sounds like you just needed to wait until they got big enough to see! Even some of my egg-scatterers that lay large eggs have fry that are almost impossible to see with the naked eye. The best way to see them is to get them to move - they tend to rest on the bottom in the dark, so if you shine a flashlight on the bottom of the tank afer lights out, you'll see them dart around.
