Yes when two lines share a common end point an angle is formed
Two rays that share a common endpoint share an angle. See the related link, "Rays forming an angle" for a picture.
All right angle triangles have a 90 degree angle and two acute angles which all together the 3 angles add up to 180 degrees.

Angle
Two adjacent angles that share a common side are said to be contiguous. Two triangles next to each other would be an example of a contiguous angle, or a figure that resembles . The line in the middle is shared by both triangles.

Not so. The two acute angles of a right triangle must add up to 90 degrees.So if the triangles have one congruent acute angle in common, they must alsohave the other acute angle in common, and then they're similar.
adjacent angle
Yes.
Ensure the common angle is not between the two common sides and is not a right angle. That is, if the triangles are ABC and DEF then make angle CAB = FDE; and sides AB = DE and BC = EF (make AB > BC and thus DE > EF) Then you will be able to draw two non-congruent triangles by making AC not equal to DF. (If you make AC less than BC, then DF will be greater than DE).
