What is the ruling on selling goods associated with non-Islamic religious holidays, such as Christmas and Halloween, and selling other goods like condoms, cigarettes, lottery tickets, certain types of medicine that contain alcohol, sweets that may contain prohibited ingredients, and toothpaste, given that the customers are non-Muslims?

It is not permissible for a Muslim to participate in the festivals of disbelievers or in innovated festivals, nor to sell anything that aids in such participation. Similarly, it is forbidden to sell tobacco, lottery tickets, and any commodity that includes something prohibited. It is forbidden to sell what is forbidden to consume or use, such as selling images of living beings, and trading in intoxicants and pigs, even if the sale is to a disbeliever, because they are also addressed by the branches of Islamic law. As for selling condoms, it is permissible unless it is highly probable that they will be used for an unlawful purpose. Regarding medications containing alcohol: it is permissible to sell them if the alcohol content is low and does not cause intoxication.
