Capricorn
Most of the "classical" constellations were named by the ancient Greeks. I believe this includes Sagittarius.
Aquila has nine neighboring constellations: Aquarius, Capricornus, Delphinus, Hercules, Ophiuchus, Sagitta, Sagittarius, Scutum, and Serpens Cauda.
These constellations all border Capricornus: Aquarius Aquila Sagittarius Microscopium Piscis Austrinus

No. All circumpolar constellations are found near the celestial poles. Because of their proximity to the poles, they never disappear from view. Sagittarius is on the ecliptic and thus (like all other zodiac constellations) not close enough to the poles to render it circumpolar.
7 constellations border Scorpius. They are Sagittarius, Ophiuchus, Lupus, Ara, Norma, Corona Australis and Libra.
Yes, Capricorn borders these other constellations: Aquarius Aquila Sagittarius Microscopium Piscis Austrinus
There are several constellations bordering Aquila: Sagitta Hercules Ophiuchus Serpens Cauda Scutum Sagittarius Capricornus Aquarius Delphinus
Yes, the Sagittarius constellation is part of a big star group. The Sagittarius constellation outlines a centaur who is carrying a bow and borders the constellations of Scutum, Scorpius, and Indus.
All of the constellations of the zodiac.
