Is it okay to use soon at the end of the sentence if I want to tell somebody how soon I will do something?
For instance,
I will be back soon.
2 I will be back to work soon.
3 I will return soon.
4 I will return to work soon.
Are these sentences okay?

Is it okay to use "soon" at the end of the a sentence if I want to tell somebody how soon that I will do something soon?
For instance:
1. I will be back soon.
2. I will be back to work soon.
3. I will return soon.
4. I will return to work soon.

Are these sentences okay?

1, 3 and 4 are correct. I would use "back at work" or "coming back to work" in 2.

Note that none of your sentences say how soon you will do something. That would require an actual timescale.

John: I'll do it soon.
Helen: Yes, you already told me that, but how soon?
John: Tomorrow morning.

Okay. Will it sound better if I change it to 'I will come back to work soon'?
2 I know that I am not specific when I use 'soon' but I just want to know if I can use it at the end of the sentences in this way.

You can.

Note that in #2 @emsr2d2 used a contraction. (See below.)

I'm going to wash the dishes. I'll be back soon.

I'm going to the store. I'll be back soon.

Later:

I'm back!

Okay. Will Would it sound better if I changed it to 'I will come back to work soon'?

Better? No. It's just an alternative way of saying it.

2. I know that I am not being specific when I use 'soon' but I just want to know if I can use it at the end of the sentences in this way.

Yes, the position of "soon" is OK in all those sentences.
