We already have 2 domain controllers in  our organization

1.world-hq1.com (having all fsmo roles)
2. world-hq2.com (this is also DC)

We want to build another dc name with world.com ( having all fsmo roles) in our organization.

How can we replicate info from world-hq1.com 2. And world-hq2.com (this is also DC)
To world.com ( which is another DC) preferably only user groups from world-hq1.com 2. And world-hq2.com

any tools we can use , they are all on premise servers

Hello,
you can do it by creating domain trust.
See for example this:

one would normally create the forest world.com and then add the domains hq1.world.com and hq2.world.com.

Just to be sure we understand your needs - Trusts between domains or forests are used for authentication purposes, so users from one domain can logon in second domain (or different forest - it is your case) by their account from first domain and vice versa. So there is no data sync only authentication request is forwarded to the trusted partner and I trust to response.

I am giving you example.

company called -Johnson-hq.com I have right now 2 DC with name as Johnson-hq1.com and Johnson-hq2.com
johnson hq1.com has all fsmo roles

now I want to add Johnson.com as I have purchased that domain into a separate DC
want to have all fsmo roles in it. but need to sync users around 5000 from Johnson-hq1.com and Johnson-hq2.com to Johnson.com

first step would be to create two way trust between these 2 forests, but how will I sync? so how will data sync?

actually my IT planner wants to finally upgrade to office 365 so that all user attributes sync from Johnson.com to office e365 instead running directory synchronization from two other dc's as he has made Johnson.com as primary tenant in office 365

OK, now it is clear. For your scenario is used Azure AD connect:

All domains will sync with Azure AD connect and Azure AD connect will be single AD partner for O365

but then what is the point in creating Johnson.com which my IT person wants

Johnson-hq is a forest and Johnson.com will also be another forest?

The best scenario is one forest but from your request it looks like your IT will not do it.
The better should be if you send me your current Domain structure.
Because if you have forest ".com" with domains world-hq1.com and world-hq2.com
then you can add third domain "johnson.com" and you do not need any sync inside, because
all domains are in one forest.
