Is it permissible to publish songs and music from children's games that contain advice, adventures, and stories, on a website dedicated to them?

Establishing a website for children can be a righteous deed for which you will be rewarded if your intention is pure and you adhere to Islamic guidelines. The Prophet, peace and blessings be upon him, commanded that children be trained in goodness and taught acts of worship, such as prayer. The righteous predecessors used to command their children to perform acts of worship to instill goodness in their souls. If Islamic law has commanded training them in obedience, then it is even more important to train them to avoid prohibitions. As for songs accompanied by music, they are forbidden. There is no harm in children's songs that are free of music and forbidden elements, and games that contain music must be removed.
