2004 Camry 1MFZ V6 Removed a few plugs and gap is fine. There NKG Iridium types.
Color of each plug is grayish almost whitish. Should i be concerned ?

That's normal.

Worry when it's bent for no reason, jet black, has carbon deposites, or covered in oil.

Is there a way to test the spark plug coils using a VOM [ multimeter ]

Listen to Toysrme.....nothing out of the ordinary with the plugs...take a pic and post it if you're really worried about it

Im talking about removing the coils, not the spark plugs. In the future, can I test these coils for resistance, like I've done on on my 94 Dodge's coil pack ?

primary resistance of the Distributorless ignition coil 1mz-fe should be: 0.5 to 0.85 ohms.
So sayeth the 94-95 1mz-fe haynes. Amen.
