4. The bridge is made out of stone.
5. The bridge is made from stone.
6. The bridge is made with stone.
(Which ones are grammatical from sentence 3 to Sentence 6?)

1 and 2 mean the same thing, yes.

3 - 6 all are grammatically correct.

In terms of grammar, all of the sentences 3 to 6 are correct and acceptable. The choice of preposition, however, can slightly alter the meaning or emphasis of each sentence.

3. The bridge is made of stone.
This sentence is a straightforward statement, indicating that the bridge is constructed using stone as the primary material.

4. The bridge is made out of stone.
This sentence has the same meaning as sentence 3. "Out of" is often used interchangeably with "of" to describe the material from which something is made.

5. The bridge is made from stone.
This sentence also expresses that stone is the material used to make the bridge. However, using "from" may imply that the stone went through some kind of transformation or conversion process before being used in the construction of the bridge.

6. The bridge is made with stone.
This sentence implies that stone was one of several materials used in the bridge's construction. It suggests that other materials may have been involved as well.

In summary, sentences 3, 4, 5, and 6 are all grammatically correct. The choice of preposition can subtly affect the meaning of each sentence.
