No. Your mass would remain the same but your weight would increase greatly.
The mutual force of gravitation between the earth and the sun would decrease if the mass of either body decreased, or if the distance between them increased.
No. The sun is decreasing in mass (fusion) over time whereas a black hole would increase in mass over time (sucking up astroids, gas, etc). So over very long periods of time the sun's gravitational force will significantly decrease, and if it was a black hole it would increase. Increase/decrease in mass directly affects increase/decrease in gravitational force. Since gravitation (and motion) is what causes orbit, over long periods of times the planets would have very different orbits in the two scenarios (sun vs black hole).
A decrease in density would indicate a reduction in mass relative to the volume. If the mass decreases but the volume remains the same or increases, then the density would decrease.

you increase or decrease mass by taking the mass out
Warming the air mass from below! Danny D
If a candy bar was cut in half the mass would decrease.
Decrease the distance between Neptune and the sun
No. Assuming the sun's mass were compressed into a black hole, the sun would still have the same mass. The gravitational pull created by that mass would not be affected beyond the distance of the sun's present surface area.
The mass remains the same.
A decrease in the energy produced by the Sun. Energy from the sun provides heat so a decrease in this would lead to cooling.
It would make the value of the item decrease.
