They sure were!. I was one of them along with a very young Rod Stewart.

No. Everything in our world is four dimensions. 3 dimensions of space, and 1 dimension of time.
This is an area of active research. In other words, it isn't really known. One hypothesis is that within a larger "something", different universes have formed, with different physical laws and even different numbers of "active" dimensions (see below). In this case, we simply happen to live in one that has three dimensions. Active dimensions: There is some evidence that our Universe actually has 10 or 11 dimensions, but that only 4 of these (1 time dimension, 3 space dimensions) manifest themselves on larger scales. The other 6 or 7 spacial dimensions are believed to exist only at extremely small scales - much smaller than can be directly observed.
The additional 7 (or possibly 8) dimensions, if indeed they exist, would also be dimensions of space and time, but they would be more curved than the more familiar 4 dimensions of space and time that we know and love.
Centrifugal force is an illusion, and doesn't really exist.
Simple...the second dimension has 2 dimensions. Think of a coordinate plane... it has 2 dimensions... height and width. This plane is the only area that they can be on. If they were not on the plane they would be in a different dimension. So to answer your question... if it wasn't flat... it wouldn't be 2 dimensions. Better yet, the reason why the second dimension is flat is simply because only two vectors exist within a two dimensional figure. (up/down, side- side)
Yes. The 4th dimension is time. According to String Theory (which is unverified), there may be as many as 11 dimensions, but dimensions above the fourth are hypothetical.
in reality they don't exist, but are parallel universes
no,A solid equire at least three dimensions to exist.
No. Space is a set of three dimensions in which things can exist.
No. Everything in our world is four dimensions. 3 dimensions of space, and 1 dimension of time.
Not sure what you mean by "recognized," but a worm-hole could (in theory) exist perfectly well in our Universe of three spatial dimensions. You couldn't really DO much with worm-holes in our Universe (they are too unstable) but they could exist.
The word is dimension. And no dimensions other than our own are known to exist. Everything about other dimensions is purely a theoretic exercise.
Bald eagles are endangered, but they really exist.
No, Medusa does not really exist. She is a fictional character from mythology.
No, It does not exist!!

No, super hero didn't really exist
