Yes, they make a lot of 5nm and 4nm parts for Qualcomm and others. For example, the Snapdragon 8+ Gen 1 is based on TSMC's 4nm (the regular 8 Gen 1 is based on Samsung's 4nm). AMD's Ryzen 7000 series (Zen 4) uses TSMC's 5nm.
Apple tends to have the best margins and is willing to pay upfront for TSMC's capacity so they generally get it ahead of other customers. However, there are reports that Intel will be using TSMC's 3nm: https://www.windowscentral.com/intel-apple-tsmc-3nm-report. Intel has confirmed that it will be using TSMC's 3nm tech in its 2023 products, but hasn't said which products. Maybe we'll see Intel laptop chips at 3nm, maybe it'll be high-margin datacenter chips, maybe it'll be something for enthusiasts on the desktop, maybe it'll just be the GPU for chips made with Intel 4 (5nm): https://www.extremetech.com/computing/338679-intel-may-drop-....
