The Angle-Angle-Side (AAS) Congruence Theorem can be proven using two main reasons: first, if two angles of one triangle are congruent to two angles of another triangle, the third angles must also be congruent due to the triangle sum theorem. Second, with an included side between these two angles, the two triangles can be shown to be congruent using the Side-Angle-Side (SAS) criterion, as both triangles share the same side and have two pairs of congruent angles.

It does not necessarily prove congruence but it does prove similarity. You can have a smaller or bigger triangle that has the same interior angles.
To prove triangles are congruent by the Hypotenuse-Leg (HL) theorem, you need to establish that both triangles have a right angle, and that the hypotenuse and one leg of one triangle are congruent to the hypotenuse and one leg of the other triangle, respectively. An additional congruence statement that could be used is that the lengths of the hypotenuses of both triangles are equal, along with confirming that one leg in each triangle is also equal in length. This information is sufficient to apply the HL theorem for congruence.
Yes, the corollary to one theorem can be used to prove another theorem.
There are three main ways to prove to triangles congruent. If all the sides match, if a side then an included angle and the next side and last angle-side angle. SSS, SAS. ASA

Excuse me, but two triangles that have A-A-S of one equal respectively to A-A-S of the other are not necessarily congruent. I would love to see that proof!

You left out one very important detail . . . the statement is true for a RIGHT triangle.

It is a theorem, not a postulate, since it is possible to prove it. If two angles and a side of one triangle are congruent to the corresponding angles and side of another triangle then the two triangles are congruent.
