Questions about example sentences with, and the definition and usage of "Hpld"

A: Do you mean 'hold on'? If so:

"Are you ready to go?"
"Hold on, just putting on my shoes!"

"Hold on a second, my shoelaces have become untied."

"Hold on, why did you go there in the first place?"

I think it's similar to ちょっと or ちょっと待って in Japanese.
