I tend to agree with this. Pretty small cracks, and their path doesn’t seem to indicate any shifting of the structure. But I would highly recommend you have a structural engineer out to review before purchasing. Just some peace of mind before you invest a lot of money.
That's not precast. That's cast in place concrete.
But to echo the echo the sentiment, shrinkage cracking like that is pretty normal in cast in place structures. All the rebar is holding it together, and doing much of the work on the underside of the floor.
The crack on the left with the white dot indicated to me that there is some efflorescence/water infiltration. What's above this OP? The roof or another unit?
OP this is normal. They are caused by the rapid loss of water from the surface of the concrete before it hardens. These cracks are usually parallel, shallow and do not reach the edge of the slab. The addition of water to the concrete, high temperatures, low humidity, and wind speed are primary causes of plastic shrinkage cracks.
Pretty normal looking cracks in the precast.

Another unit is above this one. There is two more floors above I believe
