Can I use the same 5pcs speaker in the AV system? Is this perfect?

The speaker is designed to radiate vertically because of the driver alignment. Putting the speaker hortizontal will probably wreck havoc with the sound stage. One end of the speaker will be pumping highs and the other end will be pumping lows which will make intergration with the mains very difficult. I would go with a dedicated center speaker positioned as the manuacturer intended.

THANKS.
