1/ No
2/ For a given army you should have "sufficient" commanders plus a couple more in case the other get killed (else everyone routs !) - not counting SCs...
3/ Not really, they are generally to weak to warrant huge equipment spending - but there may be exceptions : Assassins, Heroes, big badasses like Abysians...
4/ That's mainly an Ulm decorum thingie - Variety in sameness

! There's one main difference between the Groups : armor type and shield or not (prot ranging from 15 to 20). Second difference in weapons is way less important.
5/ They are usually cheaper, and it's safer to have 2 commanders for 50 troops than only 1, lest he be killed in battle by a stray bolt or spell
6/ Linked to 4/ : the various flavors of Ulmish canned-commanders have slightly different fighting abilities - but usually they shouldnt fight at all...
