Logistically I can’t get to the synagogue to pray throughout the week. When praying alone at home using one of my siddurs I have, I don’t know if I’m reading too many sections, like ones that require minyan or what. MY QUESTION - What are or are there, a required minimum sections to read/pray through in a siddur?

Most important minimum for men in the morning are the brachot of the morning; then Baruch She'amar- Ashrei and Yishtabach, then Shema Yisrael with the brachot before and afterwards, then Shmoneh Esreh and Aleinu.
