Question

Can we use じゃないです in place of です to negate the sentences, "あれもたかいですね” and ”おいしいですよ”, which mean "That one is too expensive" and "It is delicious" respectively?

No, they cannot be negated using じゃないです because たかい and おいしい are not nouns. They are not grammatical and would need to be conjugated differently i.e. たかくないです and おいしくないです.
