yes and no... if it was in Indonesia and their was context this would be completely fine as they try and use the least words possibly normally.
you could also say berapa sepatumu punya 'how many shoes you have'
If you said berapa sepatumu, and they didn't understand, you may hear 'jumlah' asked back to clarify or 'saya punya' for 'i have?'
this sentence is not very good in my opinion, Jumlah is not used very much in normal Indonesian day to day, only really used when you or an Indonesian person is clarifying if there is confusion and commonly the word jumlahnya 'the total" may be heard if they are confused about if you want to pay for everything or if you are paying for multiple people for example it may be used instead of 'harganya' (the price is). at least that was my experience spending a few months there.
however i found 'semua' for all is used alot instead of the above as well.
not sure if that was helpful haha,
