Answers:

If the Sun loses mass, then slowly we move away from the Sun. Still we will be going around the Sun.

The sun mass is 1.989e30 kg. It loses 4.4e9 kg per second. No significant change in earth speed or orbital diameter occurs due to this, though the day length has increased by 1.7 milliseconds during the last 100 years. Orbital speed - because of its elliptical orbit, it is moving faster when closest and slowest when farthest, but its rotation rate is constant.

No, It means that the earth is getting closer to the sun year by year.

If the SUN lost mass, the gravitational field attracting the earth would reduce.
The earth would move outwards giving up some kinetic energy to the gravitational field.
Therefore not only is the kinetic energy of the earth lower, its orbital period would be slower again due to the increased distance required per orbit.

If the earth GAINED mass,( from being bombarded with particles that have left the sun) then what happens depends on the momentum of the mass that hits the earth.
If there is no momentum in the direction of motion of the earth ( most unlikely ) then the conservation of momentum would reduce the speed of the earth.
The consequence would cause the earth to "fall" slightly closer to the sun. Giving a slightly faster orbital period.

So often there are multiple factors working in different directions.

WHICH speed are you talking about. Orbital speed or rational speed?

I had to research this. it turns out it would not change noticeably in human life time, but over VERY long periods of time earth's orbital speed WOULD get faster because a very SMALL percentage of the Sun's mass is being converted into energy. i suggest you read the whole article, not just the part I've copied and pasted below.

"..Above, we said that in 100 years, the Sun's mass will decrease by 6.6 parts in a trillion. Therefore, the orbital separation of the planet will increase by 6.6 parts in a trillion and the orbital period will increase by 13.2 parts in a trillion. If the planet in question is the Earth (whose orbital separation from the Sun is around 150,000,000 kilometers and whose orbital period is 1 year), the Earth-Sun separation will increase by about 1 meter, and the orbital period will increase by about 0.4 milliseconds! Neither of these values is large enough for us to be able to detect.

I'm not sure exactly how long we'd have to wait to see a measurable effect in the Earth-Sun orbit. Probably, there are other effects which overwhelm this one and would make it difficult or impossible to detect, even over very long time periods -- for example, changes in the Earth's orbit due to perturbations from other planets. The Sun's mass is also changing due to other effects (such as the solar wind), but over the long run these are probably smaller than the Sun's mass loss due to fusion (as pointed out in another Ask an Astronomer site's answer to this question)....''
