At the Juniper EX4200 you would create an AE that contain the multiple links, and then run LACP on top of this.  LACP enabled is not default action for a Junos AE.  On the Arista side, both their MLAG ports on the different switches should be configured to run LACP as well.

Yes the standard ae with lacp is standards based so will be compatible with the MLAG link.
