Well it is written in the picture . Use 2 dual opamps .

Ok thanks.

Another question: what is the difference to use two with 2 opamp or one with 4 opamp?

Maybe they recommend 2 duallies to avoid the oscillator from bleeding into the buffer. Maybe having everything "under the same roof" in a quad may create noise problems.

Just guessing.
