11 sides
The diagonal of a polygon is a line segment that joins two non adjacent vertices. So for a n-sided polygon, each vertex can be joined to n-3 other sides. So there ought to be n x (n-3) diagonals for a n-sided polygon; however, each diagonal is counted twice, once by the vertex at each end. So the number of diagonals is:
diagonals = n (n-3) / 2
So for 44 diagonals:
44 = n (n-3) / 2
88 = n2 - 3n
n2 - 3n - 88 = 0
(n - 11)(n + 8) = 0
n = 11 or -8
Since the number of sides can't be negative, the number of sides is 11, a hendecagon (or undecagon)

Yes. Regular polygons with an odd number of sides are also symmetrical.
All regular polygons with an even number of sides. Irregular polygons with an odd number of sides can have parallel sides. There are also non polygonal shapes that can have parallel sides.
Any two polygons with a different number of sides are not similar.

Yes, regular polygons will have all sides equal length, and all angles the same. If two polygons of the same number of sides are 'regular' then those two polygons will be similar (they may be scaled, for example).
All polygons have an equal number of sides and angles.
