Slivers

Say all slivers have vigilance, with a total of 3 slivers on the field attacking could they all tap due to  {Magma Sliver} and still deal damage since they are declared attackers?

Yup. Declare them all as attackers, after that is done you can tap them for the magma sliver effect at any time.
