I read somewhere Cassiopeia has a star that is similar to our own sun.

I live in the Bay Area

My understanding is that potentially all stars have planets orbiting around them.

What are these 2 stars and what are their differences?

I have seen such star

At night when the stars appear you can see that one of them is really shinning

How would plants react to moving to another star?

I see many stars that are even bigger relative to our sun than our sun is to most of the other planets in our solar system.

I was in the Chicago suburbs and there was a very bright star to the south or southwest.

In Northern Britain at this time of the year, one very bright star appears before any other.

Also, what size star is needed to spport three livable planets?
