At a tourist counter

At a tourist counter, to ask if you can take one of the brochures(pamphlets/booklets/guidebooks) there, by pointing at them, is it okay to say:
Can I take one of these?
Can I take this?

And if you want to ask for Japanese translated version, can you say:
Do you have this in Japanese?
Do you have these in Japanese?
Do you have a brochure(pamphlet/booklet/guidebooks) in Japanese?
Do you have brochures(pamphlet/booklet/guidebook) in Japanese?

Thank you very much
