Yes but he may not have a shrimp for very long

yes but sometimes betta like to snack on them

Yes but keep your betta well fed or the shrimp will be his next meal! I’ve had shrimp with all my betta and the only one that lasted longer than a week was with one particular betta that apparently was friendly

Hmmm. Is there a particular type of shrimp that might have a better chance at survival? Maybe a larger one?
