Learn Italian: Vogliamo usare parecchie ciprie. - We want to use several face powders.

Parecchie is an indefinite adjective here, meaning 'several' or 'quite a few'. It must agree in gender and number with the noun it describes. Since ciprie (face powders) is feminine plural, we use the feminine plural form parecchie.

How does parecchie compare to molte or alcune?

Parecchie sits somewhere in between. It means 'several' or 'a good amount of', which is more than alcune (some or a few) but usually less than molte (many or a lot).

What is the singular form of ciprie, and why does the plural end in -ie?

The singular is cipria (face powder). For feminine nouns ending in -ia where the i is unstressed, you simply change the final -a to an -e to form the plural, resulting in -ie.

Could parecchie be used as a pronoun instead of an adjective here?

Yes! If the context was already clear, we could drop the noun and say Vogliamo usarne parecchie (We want to use several of them). In our current sentence, however, it acts as an adjective because it is placed directly before the noun ciprie.
