Speaking as a non-lawyer, I do not think there is a pathway for you to sponsor the son of your second wife to the UK.
That is because of a confluence of two principles underpinning the Immigration Rules.
(a) Children born abroad follow the same immigration pathway as the second/less-privileged parent.
and
(b) Polygamous marriages are to be discouraged and disadvantaged in the UK, especially in immigration matters.

she was my 1st wife with 5 children and they all have British citizen now...
You have already sponsored a wife and her children to the UK. You can not sponsor any subsequent wives to the UK as a spouse. They can of course move to the UK on their own steam.
So even if your second wife wanted to move to the UK, she couldn’t be sponsored by you as a spouse. And her son's status is dependent on her, the second/less-privileged parent. if she doesn't/can't move to the UK, neither can your son.
The relevant
Immigration Rules are quoted below.
Spouses and civil partners
278. Nothing in these Rules shall be construed as allowing a person to be granted entry clearance, leave to enter, leave to remain or variation of leave as the spouse and civil partner of a man or woman (the sponsor) if:
(i) his or her marriage or civil partnership to the sponsor is polygamous; and
(ii) there is another person living who is the husband or wife of the sponsor and who:
(a) is, or at any time since his or her marriage or civil partnership to the sponsor has been, in the United Kingdom; or
(b) has been granted a certificate of entitlement in respect of the right of abode mentioned in Section 2(1)(a) of the Immigration Act 1988 or an entry clearance to enter the United Kingdom as the husband or wife of the sponsor.
Children
296. Nothing in these Rules shall be construed as permitting a child to be granted entry clearance, leave to enter or remain, or variation of leave where his parent is party to a polygamous marriage or civil partnership and any application by that parent for admission or leave to remain for settlement or with a view to settlement would be refused pursuant to paragraphs 278 or 278A.
Because your wife would fail Section 278, your son must necessarily fail Section 296.

Appendix Children caseworker guidance wrote:Sole parental responsibility
Sole parental responsibility means that one parent is unknown or has abdicated or abandoned parental responsibility, and the other parent is exercising sole control in setting and providing the day-to-day direction and care for the child’s welfare.
In assessing whether the applicant has sole parental responsibility for a child, you must consider any evidence provided to show that:
decisions have been taken and actions performed in relation to the upbringing of the child under the sole direction of one parent
only one parent is responsible for the child’s welfare and for what happens to them in key areas of the child’s life, and the other parent does not share this responsibility for the child
one parent has sole responsibility for:
- making decisions regarding the child’s education, health and medical treatment, religion, residence, holidays and recreation
- protecting the child and providing them with appropriate direction and guidance
If this evidence is not provided with the application, you can contact the applicant to request it.
Note that:
sole responsibility is not the same as sole legal custody - a parent may have sole legal custody for a child where the other parent is still involved in the child’s life
making significant or even sole financial provision for a child does not in itself demonstrate sole parental responsibility
where both parents are involved in the child’s upbringing, it will be rare for one parent to establish sole parental responsibility
sole parental responsibility can be recent or long-standing – any recent change of arrangements should be scrutinised to make sure you are satisfied this is genuine – if you think it necessary, you should contact both the applicant’s parents for more information
The question is not who is financing your son or your second wife. The question is, does anybody other than you have any responsibility and say over your son's life? Your second wife needs to be completely out of your son's life, with her having no role in his life, for you to qualify as having sole responsibility. It is not just about finances, it is a much wider assessment than that.
Then again, I am not a lawyer, merely pointing out the relevant sections of the Immigration Rules. Given the boom in oil prices right now, you may be better able to afford lawyers who could either provide you alternatives, or take the government to court and get these section overturned.
I am not a lawyer or immigration advisor. My statements/comments do not constitute legal advice. E&OE. Please do not PM me for advice.
