Yes They sure can
This question is kinda like asking "How do we talk?" They do not exactly talk... And it Depends on what type of seal you are talking about. And what age, and what gender too. Arctic seals can make complex calls. There's up to 100 different sounds ranging from growls, whistles, chugs, groans and moans to upsweeping whistles and chirps. In the far north, the males use their long-range calls to attract distant females. Usually the male seals do most of the calling, to defend their territory or to attract females during the breeding season. Bearded seals and Weddell seals in the Antarctic produce a long descending whistle that goes on for 10 to 70 seconds. And they are doing it underwater, with their mouth and nostrils closed, so there's no air coming out, and they're literally shouting. On the other hand, harbor seals usually use quiet calls. But... Yea... Different seals have different calls for different reasons.
No they can not talk to each other because their languages are different just like humans have different langueages: French, German, English, Espeniol, and also Greek.
