Inherited some cowboy boots. Need some help/advice.

I just inherited these various pairs of boots and was looking for some input. All of these are around 20 years old.

1. Brand: Cimarron (thinking these are alligator but not too sure)
2. Brand: Custom? There’s no identifying marks. (Pretty sure crocodile just wondering if they look like prints)
3. Brand: Custom? No identifying marks (Looks kinda like elephant and has a suede texture to it. Maybe prints?)
4. Brand: Tony Lama (Ostrich, needs resole but is it worth it?)
5. Brand: Tony Lama (Teju Lizard, needs resole and has damage on toe. Worth it to fix and resole?)
