Help with a question

I was wondering if anyone could help me with a couple of questions please,
I’m trying to say
“which day is Alan playing guitar”
“What is Sue doing on Sunday”
The questions are for a practice group, thank you

Pryd bydd Alan yn chwarae y gitar?

Pryd mae Alan yn chwarae’r gitar?

Pa ddiwrnod ydy Alan yn chwarae’r gitar?

Beth mae Sue’n gwneud ar ddydd Sul nesa?

Diolch Margaret, its for our practice group
