How to set minimum and maximum quantities or amount for a store?

You need the Min/max quantities for woocommerce plugin for that. and for ammount use this code:

`/* View error notice when you click Proceed to cekout, just before checkout. Coupon acceptance – when using a coupon acceptance of an order for less than the minimum amount order allow to next step
This modified code adds support for:
1. Price in admin settings with VAT and showing in error notice in VAT !
2. Showing error notice in ceckout (minimum purcharse)
3. Reflecting the use woo coupons (disable minimum purcharse in use coupon for concrete vendor and order continuation)*/
