Yes, and it would have to be a right angled triangle as the sides are in ratio 3:4:5 6^2 + 8^2 = 36 + 64 = 100 = 10^2 . Good old Pythagoras!
Any number between 3 and 15
Yes and the given lengths would form an isosceles triangle.
To determine if three numbers can be the side lengths of a triangle, they must satisfy the triangle inequality theorem, which states that the sum of the lengths of any two sides must be greater than the length of the remaining side. For example, the set of numbers 3, 4, and 5 satisfies this criterion, as 3 + 4 > 5, 3 + 5 > 4, and 4 + 5 > 3. Thus, 3, 4, and 5 could be the side lengths of a triangle.
No. Angles don't have anything called a side length. However, one can use trigonometry to compute the angles of a triangle based on the side lengths of the triangle (triangles do have side lengths).
Because all side lengths are different, it must be a scalene triangle.
If its a right angle triangle then its side lengths could be 3, 4 and 5
Any number between 3 and 15
That number is called the "perimeter" of the triangle.
Yes and the given lengths would form an isosceles triangle.
The dimensions of the scalene triangle could be 7 by 5 by 3 inches
That depends on what the side lengths are. Until the side lengths are known, the triangle can only be classified as a triangle.

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.

An isoceles triangle! It has two lengths the same!
