You cannot send funds in trading accounts to others if the receiving account is registered in a different name.
Internal fund transfer between accounts is only possible when the accounts are owned by the same person.

It is the same also for your family, corporate and partners.
If you want to send the money, you must withdraw your funds from MT4 accounts then send them to others by yourself.
