First: Morality is rooted in biology due to the biologically enforced hierarchies and behaviors we follow as relatively 'pack' animals.

For example: https://www.youtube.com/watch?v=meiU6TxysCg

Monkeys understand fairness which is what we perceive as morality.

There is a reason the old testament speaks of ' an eye for an eye'. While that is a moral judgement it follows a very fundamental game theory principles: the copycat system.

So think of the world as a giant machine learning algorithm lead by death that selects what works by death. Later that same choice gets reinforced biologically.

At some point of our evolution some innate understanding of 'fairness' was imposed on us just like on the monkeys.

Having said that the morality we build on TOP of our fundamental level seems to me to have surpassed what we are intrinsically bound to follow and understand many times already.

Are morals subjective based on perspective?

To answer the question: Morals are fundamentally rooted in common shared innate understanding. But from them comes an entire subjective class of morality that we can refer to as 'modern' morals.

Is right and wrong or "truth" subjective based on perspective?

TRUTH is never subjective. Truth is just objectivity. People can have limited access to evidence and hence obtain different 'perspectives' but TRUTH is never subjective. It just is.

Right and wrong are subjective though. Especially in hindsight.

Is there one morality or can two people from two different cultures both be moral but have opposing views?

As I said: a fundamental intrinsic layer of morality on which all cultures have built in some way. Two views can be moral to different people.

Is right and wrong based on perspective, or is there only one right and wrong?

Again: right nad wrong are subjective. CORRECT/FACTUAL and FALSEHOOD are not.

Is truth dependent on perspective? Or is there only one truth?

This is repeating. I think you are using the words TRUTH and MORAL to mean similar things when they are very different
