You don't really have good units for Arena, but here:

Ciara lead     Quaid     Ruby    Farlon    Semira (6*)

when you have enough cost (as in all 7*):

Quaid lead    Farlon    Semira    Grybe    Fadahl   (try to summon Selena and replace Fadahl with Selena)

or

Michele lead    Quaid     Semira    Grybe    Fadahl (same as above)

Spark:

Rosetta lead    Shera (6*)    Ciara     Ruby     Ultor     HP buffing and/or BB utility friend (like Haile)

when you have enough cost:

Avant lead    Shera    Ciara     Semira    Ruby    Spark buffing friend

Unfortunately, I can only give you a 7* squad for Raid cause I never used 6* in it so I can't really make judgments on how units perform, but here, all 7*:

Avant lead    Shera    Semira   Ultor    Tridon    Spark buffing friend

As for Trials, you can't make a single squad for Trials because they're all too different from each other.
