How are bases different from alkalis? Are all bases alkalis?

Main difference is that bases that dissolve in water are called alkalis and bases that don't dissolve in water are only bases not alkalis, so we can say all bases are not alkali but all alkalis are bases. Bases and alkalis are typically metal oxides, metal hydroxides, metal carbonates and carbonates of molten hydrogen.
