Not really.

Protocols like USP-PD or QuickCharge require a direct connection between
the power source and the device being charged, were USB-PD requires
USB-C as well.

USB hubs are usually not designed to power devices except when they come
with their own power supply to make sure that every port can be powered
with 4.5 (USB 2) to 9 watts (USB 3). They will most likely only delivery
100 mA per port and refuse any higher requirements.

A better choice is to use a charger with multiple ports. Up to 4 ports
in a single charger are not hard to find. There are also power banks
which provide multiple ports.
