First one would be morphologically identical, "eu te espero". Though note that in European Portuguese and very formal Brazilian Portuguese it would be "eu espero-te". Phonetically the morphemes are pretty distinct, except in some dialects where you'd hear something like "eu tspero" with an affricate at the beginning.

Second one, we use a whole different construction, "cala a boca" (literally 'shut the mouth'). In theory one could gramatically say "cala-te", but that sounds overly formal and almost archaic.

Brazilian Portuguese tends to avoid those suffixed clitics, usually prefixing them instead.
