We've never seen Hawkeye nor Wasp or Ant-man so let's assume:
Hawkeye: Normal strength and figthing abilities similar to those of Black Widow. Trick Arrows: net, electric, normal, boomerang and small explosives.
Wasp: Normal strength and powers similar to those of the 616 Universe.
Ant-man: Normal strength (when in normal size). Cannot go giant. Powers similar to those of the 616 Universe.
All characters can only use the pwers/abilities shown in the movies/series. Nick Fury will not figth unless you find it necessary.
