We don't know what that is. Is this 1 1/4" long or is that 13' long? Don't know what we are looking at.

Put a tape measure or ruler down for size reference and get a closer picture of the damage.

I will get better pictures tomorrow the first ones are like holes in the cement the biggest is about 1/3 inch deep and 1 inch across with a bunch of other small holes around it. The second one is about 6 inches long and almost looks like a foreign object in the cement

The fix depends on what you will accept , easy thing to do is grind them smooth and fill them.

Should have put in a concrete floor, not just a cement one.

Wow. Looks like "spauling."
Did you track any salt in the garage? There sure looks like contaminants in the mix. Find out who the concrete company was and get them out to look at it. Somebody owes you a new floor. The deal is to figure out who. Expect the contractor who installed it and the concrete company to point fingers. Does your state have a Registrar of Contractors you could lodge a complaint with?
Get on this right away.

Can be filled with an epoxy based patch. Grind flush.
However, I wouldn't bother unless you will epoxy-coat as the patches may stand out a bit.

The question is, are these areas expanding?
This is a relatively new pour. If you only have a few area that are stable and not getting worse, as Scotty recommended, you can grind and re-float them prior to painting. If the floor is slowly abrading in multiple areas, the whole pour is suspect.
If these areas are isolated and not degrading further, then a repair is a viable option. One of those looks like a tool may have been dropped into the mix later in the working process and filled in with loose creme. That creme may have been watered down and has little strength, hence the decay in the surface with traffic.
To know for sure, get a pressure washer and hit the damage. If it grows and then stops, try other areas that appear undamaged. If there are more, I would treat the pour as suspect. If your areas grow by 50% and then the decay under water pressure stops, you probably have some surface anomalies that can be ground and filled prior to painting.
Either way, you need to find out and a 3000+ psi pressure washer is a great way to check the concrete condition. Plus, if your aim is to epoxy coat anyway, you will have removed the creme dust if you do the whole floor. Takes awhile but, with a roller work seat, you can get a lot done in an afternoon.
Should you find the washer pulling up more and more areas of decay, definitely get the contractor and supplier involved, if you know who they were.

It was poured April 15th the garage isn't finished yet still waiting on doors. I noticed the big spot after a heavy rain before the roof was on. The builder came out today to look at it and put hydraulic cement on some of the spots. When I came home I observed 5 or six spots like this

Pressure wash it.
If it crumbles, get a new floor.
If its solid and holds up, have your contractor epoxy your floor to cover the boo-foos. Make sure you get to pick the installer.

That's what happens when you just use cement instead of concrete ;-)

That ***** sory to hear. hopefully the gc can get a fix. maybe you can mention that he can epoxy the whole floor for free, as opposed to replacing the floor?
that would be cool with me, i think.

Cement is a constituent part of concrete. Its the binder, gluing the aggregate together. And, its the most expensive part of the mix.
No one, especially a contractor, is going to do a garage in cement only. It would be prohibitively expensive. The difference between 5000 psi concrete and 10,000 psi is largely the addition of more Portland cement to the mix.
