'Advice' is a noun meaning "an opinion or suggestion about what someone should do." Advice is a noncount noun (or mass noun) which means it does not have a plural form.

How do you say more than one advice?

If the object really is the advice (and not something that provides or takes advice), then "advices" would be just fine. (Because in this context, "advice" would be a countable noun since you could have two of them.)
