Are these sentence's punctuated correctly?

Yes, except for your question, "Are these sentence's punctuated correctly?"
"sentences" does not need an apostrophe, as it is only a plural form.

Yes, these sentences are punctuated correctly.
"In the year 2000, 25,000 cases of breast cancer are anticipated." This sentence is correctly punctuated. The comma is used to separate the introductory phrase "In the year 2000" from the rest of the sentence.
"Peter Preziosi, PhD, CAE, is the executive director of AHDI." This sentence is also correctly punctuated. The commas are used to separate the different elements in the series of credentials after the person's name.
"It was an exhausting, complicated surgery." This sentence is correctly punctuated as well. The comma is used to separate the two adjectives, "exhausting" and "complicated," that are describing the noun "surgery."
