Will stopping my query rollback all my queries I have started a Query like the following in SQL Mgt studio:

Currently running sp_who I can see the Query is running for TBCompany_503
My question is that if I Kill the process for TBCompany_503 will it rollback the changes for TBCompany_500 - TBCompany_502 ?
Reason I want to stop it, and run them separately.
Not unless you wrapped those calls in the same transaction, otherwise those previously ran updates are committed already.
