100% as a decimal is 1.
As given in the question, it is a terminating decimal.
A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. A decimal representation does not require a decimal point. So the required decimal representation is 86, exactly as in the question.

no, it is an infinetly nonrepeating decimal

The only real number that is non-terminating and non-repeating is Pi (pie)
That specific number is rational, yes. However, there's a pattern there (2,1 zero, 2, 2 zeroes, 2, three zeroes, 2, four zeroes), and if you're asking if the infinite nonrepeating decimal following that pattern is rational... no it is not, that kind of being what "infinite nonrepeating decimal" means.
Yes, However, it is not defined that way. It is defined as a number that cannot be expressed precisely as a ratio of two real numbers (a fraction). But that is equivalent to a non-repeating decimal.
Yes.
Yes.
A nonterminating number does not end. An example is the fraction 1/3. When written as a decimal, it is a nonterminating number. Also pi is a nonterminating number. Some nonterminating numbers are repeating, some are nonrepeating. But they just don't end.
Irrational numbers.
