Number of enol forms of acetylacetone
I have drawn the enols and keto forms of acetyl acetone . The ones with equality are the same structure just flipped along the line I have shown on right . I don't see how your first structure had a chiral carbon atom because the carbon you marked is bonded to two hydrogen atom .
Regardless I am also getting 3 stable forms . One could say we would have another pair of enantiomers of cummulated alkene . But that is generally not considered stable . So I didn't include that .

thinking about anything. (But pay attention to the traffic, of course.) Somewhere between 5 to $\pu{10 min}$ is a break which helps me to clear my mind, leave a rut of thinking too intensely. This may be way better than a chat in the coffee/tea kitchen (a potential trap, since colleagues of yours feed you there with new ideas [possibly unrelated, but eventually scattering your thoughts further]).More
