4. - Protection phrases forom toxic people - Part 1

This is slightly ambiguous - it could mean the phrases are for the toxic people to use, or for you to use on the toxic people. But in context it's fairly clear it means they are for use on toxic people.

An unambiguous way to say it might be something like "Phrases for protection from toxic people", or "Protection phrases to use against toxic people".

2. I don't want to touch on the subjectget into that topic.

Grammatically it's okay, but this might be a more natural thing to say.

3. I don't haveneed that need right now.

Again grammatically okay but more natural to use "need" as a verb.

5. You can't do totreat me like that.

This seems closest... "you can't do to me like that" is wrong, you might say "you can't do this to me", or "you can't do things like that to me" but "you can't treat me like that" would be a very natural way to say that someone is acting towards you in a way you don't like.

6. I don't see the subject foranything to discussion.

Or "I don't see it as a subject for discussion", "I don't see any subject for discussion".

7. It's disagreeable to me think it's unpleasant.

Or just "It's unpleasant." They seem closest.

"It's disagreeable to me" is grammatical and makes sense but a bit of an unusual way to speak, we don't often use the "to-me it is ..." (мне неприятно) construction that Russian loves so much :) we're more likely to use verbs, I think, I feel.

I know better what I needwhat's best for me.

Again, grammatical and makes sense but unusual, can't really explain why. You might say "I know better than you do what I need", but that feels very aggressive to me.

I can't do it.

"it" is fine, but you might consider if "I can't do that" would fit better.

I don't take your wordaccept what you're saying.

Not sure exactly what you want to say here? But this seems likely.

It doesn't suit me.

This is okay, but maybe a little unusual. When we say "It doesn't suit me" it's more likely that we're talking about a piece of clothing that we think looks bad when we wear it. But in context it should be pretty clear.

It doesn't resonate with melike the sound of that.

Or "it doesn't grab me". More idiomatic ways to say this. Again, grammatical but a little unusual. We do use "resonate" but I think not quite like this - I would say "That film really resonated with me", or I might use it to hedge "It's a good book, I don't hate it, but... I don't know, I'm not resonating with it. So I might stop reading it."
