Yes. There are thousands of different solar systems in milky way, the same galaxy as ours exist in.
Technically, no, because our system is named for our star or sun, "Sol". Hence, Sol-ar or Solar system. The question becomes, "Is there another star system entering ours?". In general, the parts of the universe are all moving away from each other; however, there are a number of small galaxies that appear to be slowly (millions of years) moving toward our Milky Way galaxy. But, still 'No', there are no other star systems entering ours.
Libra
The only planet anywhere known to have life is ours: Earth.
It showed that there were solar systems similar to ours elsewhere in the galaxy.
Yes we believe most single star solar systems will have a simiar structure to ours. Where the star has a binary companion (or more companions) it is more difficult to precict that an oort cloud would be stable over time....we dont know.
Yes, there are several.

The Sun is the center of ours
not in ours
No one knows how many planets are in our nearest solar system, Alpha Centauri.
Jupiter
The other galaxies around ours and their contents.
Libra
As there is only one Solar System - ours, it's difficult to comment on the other four.
Most solar systems have one star, like ours does. Some have two stars, known as a binary system.
Of course there are.There are millions of galaxies just like ours. where there are similar to our, solar systems
