The seven sides, in order, must be congruent, as must the seven angles.
Some are some are not. Two regular pentagons with one equal side are congruent.
The term congruent is used in comparing two geometrical figures, it does not fit in this context. The angles of a regular polygon are equal.
yes if they have sides of equal length
There are infinitely many such polyhedra. A regular dodecahedron, for example.
For two 7 sided regular heptagons to be congruent they must be identical in shape and size.
The seven sides, in order, must be congruent, as must the seven angles.
They have all epual sides
Perimeters must be the same

Yes, that's what makes them congruent!
