Those look like star birth areas. Not uncommon, but not common either.
How many arms..?
Star overlap?
Star overlap, I'd say.
Not necessarily- different galaxies are different ages and sizes, what you have to look for is gravitational interaction between the two.
Nice ring!
Small elliptical galaxy overlapped by a larger spiral.
Star, probably.
Haven't seen this before... any idea what's going on?
