Just afraid one of the address being hacked, I understand it also impossible to be hacked, but still possible.
Also need few hot wallets to be use by me and my family.
(Also I can give different cold wallet to my family and let them manage them)
You'd need to create several new wallets, each with their own seeds and then split your coins across the different wallets.
In any case, you can use the "pay to many" option in Electrum and do one transaction that sends your coins from Address1 to Addresses 2, 3 and 4... and save a little on fees. Especially because fees are just insane right now.
