If you boiled honey, sugar, and lemon juice in water, would the solution become semisolid when it cooled down?

Try it! There is no way for us to tell! We do not know the portions of each nor how long it will be boiled.

That would depend on the amounts of each and the volume of water, but basically no. Water won't be come solid, nor will lemon juice. Honey is liquid at room temp. Only sugar is a solid, and once dissolved in the water, it would only really precipitate out when cooled.

It will, except you overheat it, then it will become caramel candy. You can tell by the color, golden-brown will be just right. And you don't even need honey, just take white or cane sugar. That's how caramel candy is made.

My personal recipe is, add some thin apple slices into the mix, fry until the sugar caramelizies, take the apple slices out, and serve in a bowl of hazelnut icecream as a dessert. Women will melt just as the icecream does.

It depends on the amount of water left in it.

of course it would
