Is the ghusl valid if I start by washing off traces of semen, then make the intention and say Basmala, and wash my hands three times, then wash my penis and anus three times with the intention of Istinja', then wash my hands three times, then pour water over my entire body, and wipe my head, ears, and face as in wudu', then rinse my mouth and nose three times, and complete pouring water over my entire body, then wash my feet, knowing that I combine the ghusl for janaba and for Jumu'ah in the same manner?

There are two types of ghusl (ritual bath) after its cause occurs: a complete ghusl and a sufficient ghusl. The complete ghusl has a specific procedure as mentioned by Ibn Qudamah, quoting Al-Khiraqi, which includes ten things: the intention (niyyah), saying "Bismillah," washing the hands, performing ablution (wudu), and pouring water over the entire body. As for the sufficient ghusl, it is enough to make the water reach the head and body, along with rinsing the mouth (madmadah), sniffing water into the nose (istinshaq), and having the intention for ghusl and wudu. This is sufficient to remove ritual impurity (janabah). Performing ghusl with the intention for both Friday prayer and janabah is sufficient for both, as the foundation of ritual purity is based on overlap.
