Hello, tard here no knowledge of any of what i'm talking about. Just wanted to see if people had any answers.
1)
If it is possible by some miracle that time machines were a thing in the future, would it be possible to go back in time before you were to die of old age. Meaning relive your life in the same way with no copy of you of that lives alongside you while you relive your life?
2)
If you are to do the same thing as the first subject. Would there be possibilities of being to change your own life, breaking how you experienced your life before, making dramatic changes to your old life. But still living in that same timeline where you also did some stuff that you had done before.
3)
Is there any way that if you made different changes to your old timeline that you would be able to make a new timeline where everything else turns out to be completely different, you've basically made a new branch in time or made a new universe. That would be completely different.
4)
Would there be possibilities to where time has not predetermined what will happen, and with this knowledge you'd be free to do whatever you would want to. Nothing would be predetermined.
5)
If some or many or all laws unknown and know where to be non-applicable in other universes but still had surviving and striving species intelligent enough to do such things as visit other universes or break free from time, would it be possible that they would find us and show us what they have experienced, and give us first hand experiences as well, would their lives be predetermined to as they would visit our predetermined lives or would they have control of themselves and what happens around them and vice versa.

You can't go back in time.
You can theoretically travel faster than light. This allows you to be "from the future" but you still wouldn't be able to interact with the past.
What's done is done, you can't relive your past unless you consider that the vastness of the universe means that there's a chance there's another earth where everything is and happens exactly the same as it has here.
You could go there and replace your alternate self.

Wouldn't there be a universe where you could go back in time though, where some laws wouldn't apply and you were free to do as you pleased, going back in time or forward, such as in #5), where you could have that universe come to us, able to not be applicable to our universes laws and do as they pleased.

String theory is a meme
Time is not a thing. Travelling through it is not a thing either. You are in a reference frame. You don't experience time, you experience events. Your consciousness is discrete, finite and deterministic. It experiences reality as packets of information. If it were analog you would experience reality as an endless song you felt and sensed around you. If it were digital you would experience reality as each second or heartbeat.
Near death both of these modes of reality bleed into each other. Taking certain drugs can mimic this overload effect. In a normal healthy human they operate in concert to create a cohesive and stable platform from which to make decisions and plan for future events. You think things out discretely, like parsing this sentence. And you also get a feel for my general tone and form an overall mood or attitude from reading the entire paragraph.
The first type of thinking takes an amount of time we can measure, the time it takes you to read the sentence. The second type of thinking is time independent, your opinion can always change about something on a whim, this process is less understood because it's unique for everyone.
So time is an illusion of the digital part of your brain. The one that deals with natural language processing and most of your verbal thinking.

7 days remaining.
1) You would not need a time machine specifically to achieve this.
2) Yes|No -> Back to the Future 'branch theory' is more accurate.
3) See 2)
4) You would be in a 'unique branch' so technically everything you experience would be unique.
5) You presume a lot about a sentient species capacity to understand the entirety of their race/abilities. All localized space-time entities are just 'unique perspectives'.
