Generically, google for "2x5 dupont". You'll get plenty of hits for the housings with or without crimp connectors. And a crimper, if you don't have one. Crimping pins is quite a pain if you've never done that before. Buy extra so you can screw up.
Alternately, there are pre-crimped ribbon cables that should suit your needs. Search for "dupont jumpers". Among other hits, you'll see some 40-pin ribbon rainbow colored cables pre-crimped to 1-pin connectors in several gender choices. Lengths typically are 20, 30 or 40 cm. You can strip off 10 wires from the 40, remove the 1-pin housings (lift the locking tab with a sharp point and they pull off), and plug the pins into your 2x5 housing in any wiring arrangement you need.
