1:square root 3
If its a right angle triangle then its side lengths could be 3, 4 and 5
The sides of a triangle are its lengths are cannot be negative. However, you could place a triangle on coordinate system and some points where the vertices are could be negative numbers.
The list that accompanies the question doesn't contain any numbers that could be the lengths of the sides of a triangle.

162+632=652 It is, in fact, a right triangle. I see no other question that you could be posing.

Yes and the given lengths would form an isosceles triangle.
Any number between 3 and 15
If any of its 2 sides is not greater than its third in length then a triangle can't be formed.
It can't.
The last side length could be between 4 units and 10 units inclusive.
Yes
