what weapons did the native asmerican indans have?

Answer 1

the native amerindian cultures were stone age level technology in North America, and early metal level technology in central america.
This means bows, arrows, clubs, spears. In the North all tipped with horn, bone or flints (chipped stone). Usually every warrior made his own arrow/ spear heads, which means there were no significant weapon stocks.
Several wery imaginative weapons were preserved- eg a bow made from deer antlers, which is a rather difficult material to work with and which gave some outstanding performance (range/ power of shot). A few clubs had buffalo horns fixed to them, making a sharp, penetrating wound on impact. Stone headed tomahavks or stones used at the end of clubs/ battle hammers

In South/Central a lot of the weapons were stone edged- flints or lava glass chips fixed on clubs, creating a sort of "sword". Some weapons were edged with copper or bronze, but rather very few
That is understandable- there is no advantage in a bronze/copper edge against an oponent who is not wearing armour. The flint or lava spear heads were much sharper against a naked body. Used against an armoured man (eg Spaniards) these spear tips simply shattered.

No shields, helmets or armour to speak of in both cases.

Answer 2

Tomahawks, bow & arrows, spears and knives. There are probably more that I can't think of, off the top of my head. Try wikipedia, it might give you different kinds of weapons other than what I know. .

Good Luck
