We haven't sent any spacecraft to Betelgeuse, it is much too far. However, the Hubble Space Telescope has studied Betelgeuse, so I guess that counts.
No. Betelgeuse is a single star.

Betelgeuse is about 640 light-years from the sun.

Voyager 2
As of 2021, spacecraft have studied five comets up close: Halley's Comet (by the European Space Agency's Giotto spacecraft), Comet Borrelly (by NASA's Deep Space 1), Comet Wild 2 (by NASA's Stardust spacecraft), Comet Tempel 1 (by NASA's Deep Impact spacecraft), and Comet 67P/Churyumov-Gerasimenko (by the European Space Agency's Rosetta spacecraft).
Betelgeuse is approximately 642 light-years away from Earth, and its diameter is about 1,000 times that of our Sun. If we assume a hypothetical spacecraft could travel at the speed of light, it would take about 642 years to reach Betelgeuse. However, if we consider the size of the star itself, circumnavigating it would take significantly longer, depending on the spacecraft's speed. Overall, the journey is currently beyond our technological capabilities and would take many lifetimes to complete.
No spacecraft has ever landed on Mercury, but it was studied by Mariner 10 and MESSENGER.
No, spacecraft till now has made it to mercury as it wasn't allowed and was dangerous to life.
No, Voyager 2 is not the only spacecraft to study Neptune. The Hubble Space Telescope and the Keck Observatory have also observed Neptune. Additionally, the European Space Agency's Huygens probe studied Neptune's moon Triton.
No, the name Betelgeuse comes from Arabic.
No. Betelgeuse does not affect us.
No, Betelgeuse is a red star.
No. Betelgeuse is a single star.
Betelgeuse is brighter.
