Now we only plot the UMAP in the shape "●". Can we also plot the UMAP by using “▲” or “■”？

You can pass a marker as kwarg to https://scanpy.readthedocs.io/en/stable/generated/scanpy.pl.umap.html which gets passed to the marker argument of https://matplotlib.org/stable/api/_as_gen/matplotlib.pyplot.scatter.html

@Zethson I am a beginner for snRNA sequencing analysis. Could you also share me simple code for this? Because I never use **kwarg function before. Thanks very much!
