JPSS-1 and Suomi-NPP will be separated by half an orbit (i.e., 50 minute orbital spacing).
Once the satellite reaches its final orbit, it will be known as NOAA-20. The latest JPSS flyout chart/launch schedule is available at https://www.nesdis.noaa.gov/sites/default/files/asset/document/poes_flyout_chart.pdf.
