Arrowhead help please

I got these a while back from someone and I have no history on them. Does anyone have an idea on identifying these Wish I had any info but I don't even have a location. For all I know they might be fake.... Any input will be appreciated! Thanks

I see a few that are definitely repro's and the types you can buy at rock shops of museum gift shops. Wouldn't surprise if they aren't all modern.

Being from South Louisiana also, I know for a fact that these are not from our area based on color & shape.

Yeah I'm pretty sure I was told they were from some other state but like I said they prolly reproductions... I was just curious if anyone might have known, I think they may have been purchased online or something which prolly means fake
