Q1: Are they all the same in meaning? In the last two sentnces, 'for example' is used. Do we have to put a comma before 'for example'?
Q2: How do you pronounce 'Renoir'?
Do we have to stress the first syllable or the second syllable?
I could see two stress patterns in the dictionary. Which one is commonly used?
In all four sentences, "Renoir" needs to be in singular possessive form ~~> Renoir's
In sentences 3 and 4, you need a comma before and a comma after "for example" -- see Rule 2 here: http://data.grammarbook.com/blog/commas/commas-part-10/

A1: Yes, all four sentences convey the same meaning, indicating that warm colors such as orange and yellow are visible in Renoir paintings. In terms of punctuation, both sentences 3 and 4 include the use of "for example" as an introductory phrase. When using "for example" to provide examples or clarification, it is common to place a comma before it. Therefore, sentence 4 is the recommended form with the comma included.
A2: The pronunciation of "Renoir" commonly stresses the second syllable. It is pronounced as "ren-WAHR" with the stress on the second syllable (-WAHR).
