No.
I think it can. An isosceles triangle by definition has two equal sides. It is possible to draw a triangle with a right angle and two equal sides.
The word isosceles is actually a Greek one standing for: having (two) equal sides. I thought that, in English, isosceles stands for "equilateral". If not, then yes it can be a triangle with two equal sides adjacent to the right angle. (hypotenuse excluded, anyway)
No.
The isosceles triangle wasn't invented. The word isosceles is from Late Latin and from Greek isoskelēs, from iso- + skelos leg.
The word "isosceles" comes from Greek roots and means "equal leg." An isosceles triangle has two sides of equal length.
There is no such word as icociles! The word is isosceles and isos = equal, skelos = legs. A triangle with two equal legs is isosceles.

An isosceles triangle is one with at least two equal sides.

NO but every Equilateral triangle is an Isosceles triangle. That is the difference . Isosceles triangles have only 2 sides the same length. Equilateral have ALL 3 sides the same length which means that they must have 2 sides the same length, so they are a very special case of an Isosceles triangle. That is why they have a special name - Equilateral meaning 'all sides equal'. The word lateral is a reference to the word length.
The word hypotenuse implies this is a right triangle. An isosceles right triangle has sides of 1, 1, and sqrt(2), or multiples of those. So the hypotenuse = 5*sqrt(2), which is approximately 7.07 feet or about 7 ft and 7/8 inch.
An isosceles triangle has exactly two sides which are equal. (The word congruent usually applies to triangles, not sides.)
No, apart from the fact that there is no such word. The word isosceles is derived from "equal legs" and, in the context of a triangle refers to the two sides or legs of an isosceles triangle in its conventional aspect. In the case of quadrilaterals, any of the following have equal legs: a kite, arrowhead, an isosceles trapezium, a rhombus, square, rectangle, and at a stretch a parallelogram. All in all, then the adjective would not be particularly helpful in narrowing down the possibilities.
The likely word is "isosceles" (a triangle with two equal sides/angles).
