Questions

Is there a KiCad symbol and footprint for the HFD4/5?

Yes. The symbol is EasyEDA_Pro:HFD4_5 and the footprint EasyEDA_Pro:relay-th_hfdxxx, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the HFD4/5?

DIP,10x6.5mm, with 8 pins. Its footprint is drawn on this page.

Where is the HFD4/5 datasheet?

HF publishes it: the Datasheet link on this page opens it.

Where can I order the HFD4/5?

JLCPCB lists it as part C23510, with 13,473 in stock; the sellers' links on this page open their listings.

What can replace the HFD4/5?

Parts like it in the library: the HFD4/24 by HF, the HFD4/4.5 by HF and the HFD4/12 by HF. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the HFD4/5?

2 boards in 2 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
