Will steel constructions stakes (used to supoort 2x4 forms) harm the concrete if left inside the pour area? Even if driven below the top of the form? I cannot place them outside because the forms are too close to another surface.

Of concern was the possibility moisture causing rust/corrosian due to the metal having contact with the soil...and might this be a common code violation?

The important question is will you be able to remove the wood form after the pour. The steel stake is not a problem just make sure the concrete covers the top of the stake by about 1". The wood must be removable. Have you considered using a piece of "Expansion Joint material" instead of a "form" if the pour is to close to another surface, that's what it's for.
Moisture and corrosion is not a problem for a steel stake. If there is a code issue it would only be that the reinforcing steel in the slab does not contact the stakes in any way because the corrosion will travel up the stake and into the reinforcing wire, this would take several years to happen and is usually only a concern in structural concrete.

You really don't want to leave the stakes in the slab, they will cause cracking when the concrete cures, you say that one side of the form is to close to another surface, can it be used as a form ?

They should be located on the out side of the 2x4s while pouring concrete, but no, they will just ack as a support.
Good Luck

it should not affect the concrete but may be visually disturbing, try drilling holes in the 2x4 form and slip form over stakes

Yes it will cause the concrete to crack possibly in days.

rebar is metal and is left in concrete for strength so this metal will not harm the concrete either
