Can we use all the expressions? Are they all commonly used? Are they the same in meaning?

All are commonly used, but they don't all mean exactly the same thing. Close, but not exactly!

2 and 3 are the closest in meaning.

Thank you. Which one is close to #1?

2 and 3 mean about the same thing as 1.

All four expressions can be used to ask someone to give you the snacks. However, they have slight differences in meaning and common usage.

1. "Can I ask you to take down those snacks for me?" This expression is commonly used when the snacks are located at a higher level or on a shelf, and you want the person to bring them down to your level. This phrase is often used in a situation where the person you're speaking to is taller than you or has access to higher shelves.

2. "Can I ask you to bring down those snacks for me?" This expression is similar to the first one and can also be used when the snacks are positioned at a higher level. However, this phrase may be more commonly used when you want the person to physically bring the snacks to you, rather than just lowering them to your level.

3. "Can I ask you to get down those snacks for me?" This expression implies that the snacks are not at a higher level or on a shelf, but rather in a higher, hard-to-reach location, such as on top of a cupboard or inside a high cupboard. You are requesting the person to retrieve the snacks and bring them to you.

4. "Can I ask you to put down those snacks for me?" This expression is used when the person you're speaking to is holding or carrying the snacks and you want them to place the snacks on a surface so that you can access them. This phrase is often used when the person is already holding the snacks and you want them to temporarily set them down.

While these expressions have similar meanings, they each have their own specific usage based on the context and the physical position of the snacks.
