Yes if you mean in degrees
No. An isosceles right triangle is a special case. There are many right triangles which are not isosceles.
An Isosceles triangle has at least one line of symmetry but if it has more than one line of symmetry it can be an Equilateral triangle as well as a Isosceles Triangle. So a triangle with one line of symmetry is always Isosceles and If it has more than one it is always an Equilateral triangle as well as an Isosceles triangle. Example of an Isosceles triangle:
An isosceles triangle.
sometimes, but not always
A 45-45-90degree triangle is classified as an isosceles triangle.

no
No. A scalene triangle is never isosceles. An isosceles triangle has two equal sides. A scalene triangle has none.
No not always
An Isosceles triangle has at least one line of symmetry but if it has more than one line of symmetry it can be an Equilateral triangle as well as a Isosceles Triangle. So a triangle with one line of symmetry is always Isosceles and If it has more than one it is always an Equilateral triangle as well as an Isosceles triangle. Example of an Isosceles triangle:

No
An isosceles triangle.
sometimes, but not always
An isosceles triangle has two equal sides and two equal angles. A right triangle is any triangle with one angle that is a right angle. A right triangle could also be an isosceles triangle, but an isosceles triangle will not always have a right angle.
