Yes they can, however only if the cloud is a cirrus cloud. A good example of this is hail.
Cirrus clouds are primarily made out of ice crystals.
When the temperature of a cloud is below -18 degrees Celsius, the cloud consists almost entirely of ice crystals. Water droplets freeze around condensation nuclei at these temperatures, forming ice crystals that make up the cloud.
A cloud is a dense visible mass of suspended water droplets or ice crystals in the atmosphere.
When the temperature of a cloud is below 18°C, the cloud consists almost entirely of ice crystals. This is because water droplets freeze into ice crystals at temperatures below 0°C. These ice crystals can then collide and combine to form snowflakes.
Ice crystals inside of clouds are moved by circulating wind currents.
Mostly ice crystals.
When strong winds toss ice crystals up and down in a cloud, it can lead to the formation of hail. As the ice crystals are carried up and down in the cloud, they encounter different temperature zones that cause them to grow larger. Eventually, the ice crystals become too heavy to be supported by the wind and fall to the ground as hail.
The thin and wispy cirrus cloud is made up of mostly ice crystals.

A cloud is a collection of millions of tiny water droplets or ice crystals suspended in the atmosphere. Clouds form when warm, moist air rises and cools, causing condensation of water vapor into tiny droplets.
