k. for the weapons. it is possible to have a range and melee weapon on 1 unit.
the attack animation is bound the the unit and not the weapon. so that should also not be a problem.
the sound is bound to the weapon. so if you want different sounds per units you need different weapons per unit.
remove weapons from unit. there is no easy way for trigger and the way it would work is clumbsy and dumb. just go to the data editor. pick the unit and remove the weapons.
set armor... nope. can only be done in data editor. if you want to change it midgame in the data editor you need to create upgrades and than activate them in the trigger editor.
model same story
the trigger editor is nice and easy to use. but without the use of the data editor you can't create the effects you are looking for. think its time to start read tutorials or ask someone to do it for you.
